Can a car that runs 106mph and 1.71 60 foot times turn in the 11's.
It's a 70 chevell with a built 468 350 auto trans and 4.88 gears runs 12" wide slicks leaves at 3700rpm. It's a friend of my brothers I meet tonight. I told him I didn't think that MPH matches that those times. He got alittle hot, told me he'll show me this spring. He said any one can take a lite little 65 and make it fast but real man takes a 3600lbs car.  ------------------

Yes it's easy! It sounds like an 1/8th mile car. All he has to do is run a good enough e.t. through the 1/8mi. and even if the motor is peaked out before the finish line, it will still carry over through the 1/4. All he has to do is hold it below the redline. Since the rpms aren't still climbing when he crosses the line, the mph will be low. Another way is to be able to run better numbers and just hit the brakes at the end. It's called "sandbagging".
For an example, I was sandbagging in the 13 second brackets this year and I have a few timeslips that shows 13.01 @ 80 mph. I had to hit the brakes hard at the finish just to kill some e.t. and mph. It kept me from breaking into the 12's.

Sounds very questionable to me. His 60' times aren't good enough either to make the car run in the upper 6's in the 1/8 to get him into the 11's in the qrtr. Plus, his mph is only good enough for around 12.50 or so. I would have to see it to beleive it. As for his "real man" comment. Any bozo with a fat wallet can get a big block in the 11's, but it takes a real man to get a #3500 lb small block car into the 10's (like I did with my granada) on a budget.

Yeah. I'd say he's gonna have to prove it. I doubt that he can do it. I suppose he doesn't have a time slip to show you right now. He wouldn't be so touchy about it if he could prove it.------------------

Hes very specific about the MPH and the 60 ft times but then he just says 11's?
Either he has a timeslip or maybe the dog ate it? I mean it may be possible but why make the claim if you dont have a slip? At least dont get hot about it. As for small cars not being difficult... typical chebby guy. its not as if running 11s with a big block is rocket science...------------------

Ron,Here is a typical high 11 pass. 60' 1.751
330' 4.913
1/8 7.574
mph 91.74
1000' 9.899
1/4mi 11.882
mph 113.25 Taking .04 seconds off the 60' et will not be enough for him to run in the 11s at 106mph. You can take that to the bamk.  Mel's '66 could run high 11's at 90 mph, but with 1.40 60'ers and lifting at the 1,000' mark. It's all about the 60' time scoop. SteveW

Dan so your car topped out in the 1/4 at 106 miles and turned 11's ?
He said his car would be at 6500rpm at the line in the 1/4 at 106 mph right before his liminter kicks in. ------------------ SCOOP 2.26 60'S

In my experiance, most 11&12 second cars that I`ve run usually pickup at least 20 mph from the 1/8th to the 1/4 mile. Bluestreak, since you only picked up 5mph, I`d have to say that you either had a fuel delivery problem, or too much gear, causing a top end "lay down".------------------

That car had a mild 460 geared strictly for the 1/8. I never ran it through the 1/4. That was just a real example of how a car can have a 1.70 60' and still have enough gear and power to run in the low 7's. I would imagine that If I had pushed it up to redline and held it through the 1/4, that it would run high 11's and not get much over 106 mph. I really think the guy is BSing you Scoop, but it may be possible. I say make him try to prove it and beat him at the same time!!  ------------------

Both my Fairlane and Ranger have gone a tenth and a half quicker than what the erols.com site calculates. Still nowhere near a half second. If his ET/MPH is legit maybe that 468 thing just lays down at the top end that bad. It is a Chebbie after all.

Bigblocks can easily post some good e.t's if setup correctly. Mine was just a '69 Falcon with slappers, standard '69 460, ported heads with CJ valves, with a 3000 stall and 5800 rpm solid cam.

It does say he has 4.88 gears, thats a lot of gear for a big block since they dont spin as fast as smallblocks. If its set up for 1/8 of a mile then Im sure its "possible", but that doesnt explain why he cant find a timeslip... He still has to prove it.

Not gonna argue if the Chebelle can run high 11's, but that calculator is for sure bunk, at best. My 3850 lb RR turned horrible 60 foot times. I believe 1.9 or so. 1/4 MPH was best of 108. E.T. of 12.25 Not close to what that "calculator" says. Im positive my car would (will) run high 11's with just a few more ponies. Maybe the MPH around 111 or so. But at a 108, I doubt high 11's are possible.[This message has been edited by Von (edited 12-08-2003).]

Hans can you email me a copy of that please
This guy seems like a bragger but from what my brother tells. His car is real nice and runs real hard. So maybe he's right from Hans chart he's not really to far off. It was still fun telling he couldn't run those times.
Then has he's leaving he says "when you get that ford of yours into the 11's come see. So when can see who's is better".

Those numbers look pretty accurate for a perfect setup and would be a good chart for comparing your mph/e.t. numbers to see if your combo is working good. There are still several factors that can happen before the finish that would allow you to post a slower mph than the figures on the chart. If something mechanical or natural causes the car to slow down or lay over near the end as Rory mentioned, you could still post a good e.t. with a lower mph than normal.
Loosing 10mph after the 1200 ft mark will only knock about .1 off your normal e.t.., but 10mph spread over the whole 1/4 mile can amount to a whole second. Don't ask me how that works. I'm not a mathemajician. It has something to do with time and space relativity. ------------------

Is it possible to run high 11's at 106? Sure it is. Probable, not really. Generally you are looking for 110+ for an 11 second ride but there are always expections. It is possible that the guy is over-geared, blowing the tires away off the line, making him pedal it, and then tapping out way before the end of the quarter. All he said was "in the 11's" which could mean 11.99, and 106 is not *that* far off.------------------

Our '66 has the chart beat in the opposite direction. I have many timeslips at only 119 mph and 10.7 ets, the chart says you need 123 mph for those ets. MPH is how much power you're making, ET is how well you get it to the ground and make it work. SteveW

But, that chart is off a little for the powerglide equiped cars. My dads car runs around 10.15, but at around 134 mph. But it has relatively slow 60' times due to running a 'glide (no real first gear ratio ). My car, runs (well, used to) around the same et, but with 2-3 mph slower, because my 60' times are substantially quicker than his. Another example of it being off is a buddy of mine with a Jerico 4 speed equiped car that has run 10.04, but at 137 mph. He is only running a 4.11 gear, but has a real healthy 408W, so it comes on hard at the other end once it gets rolling.'Glides tenmd to leave a little soft, but then come on hard at the end.

When I get home tonight I'll have to look at my old time slips when I used to sandbag at 12.00. I remember one time at the Ford Motorsport deal at Maple Grove (1991) I was bracket racing a big-block torino. After the race he commented on how much more MPH his big-block generated than my small block. I didn't have the heart to tell him I was on the brakes ------------------

it all depends like KV said. I had some "gremlins" in mine on both ends and it went a 9.58 @ 138 right off the trailer. BUT the 60' were pitiful @ 1.39
I've changed springs and tuned on the injection some that has helped. I also had a bent Buterfly rod causing a vacuum leak.
I am also launching it harder @ 4000 Rpm instead of 3200
I expect to see some 9.10's early next year, hopefully. 60 ft times for my car should be 1.22-1.25 ------------------

Thank you Steve!
Scoop, you have mail.
The way i look at the relationship between ET and MPH is like this,whatever MPH i can get out of the car the ET should match it.
If the speed is up compared to the time turned i know there is time to be gained.
Makes sense? Last year our car ran 110-111 Mph on the average run with times between 11.75-11.90. For this season we changed a bunch of stuff (cam lifters tranny conv rear gear and fuel system)and the speed rised to 116 Mph with a best time of 11.62.According to the chart there is some ET left in the car.116 Mph is indicative of 11.30.

COOL!
My car was *unhappy* when the 60' times got down to 1.32-1.33. That poor old chassis was twisting up something terrible. If I ever get funds to build a new motor, I'm going to use a 'glide to try and calm down the launch a bit, and hopefully make the car more consistant when the track isn't very good. Even if it means the car runs a bit slower (which I'm sure it will with the 'glide), I'll take it if it means better consistancy.

3 years ago I switched from a c4 to a glide when my c4 broke, and the car slowed down almost 3 tenths. My little, relatively high strung cleveland didn't like only having 2 gears, and neither of which was really *first* gear. And my case isn't the only one like that. I have talked with several other cleveland racers, and they all experianced the same thing when they swapped to a 'glide. One guy told me that after 6 convertors, sevrla chassis changes, and 3 ring and pinion changes, they finally got the car BACK to within .05 of where it ran with a c4. But it never ran faster.

So if you take what KidVishus and BillyMac said about those combos, it sounds like you can gain about .5 second just by changing from a C6 to C4. Is a C6 that bad or is a C4 just that good?------------------

I gained about 3 tenths when I switched from a c6 to a c4. It seems most guys gain 2 to 3 tenths on average.
A c4 is lighter, and takes less power to drive, allowing more power to get to the rear wheels.
TCI published a chart years ago that showed the hp consumed by different automatic transmissions, and if I remember correctly, a c6 took 62 hp to drive, and a c4 took 28 (my memory might not be so great, so those numbers may be off a little, but they should be close.)

A C-6 is a great transmission......for a truck....they are heavy and lumbersome and (if memory serves)....the only tranny that takes more horsepower to turn is a Chrysler Torque flite or a 727.........I can not comment on a C-4 from a performance standpoint, because I have never used one.....but for a street application.....I have had nothing but good service out of C-4's....
I HAVE heard about guys up in the midwest using C-4's even behind Chevy motors......so there MAY be something to em'.....perhaps someday I'll find out for myself......

agree with steve66 and bluestreak. also would like to point out the sandbagging answer seemed to be glossed over by people saying "no way!". either the guy is overgeard/sandbagging, or he's lying. either way he shouldnt be bragging. his car isnt impressive considering the cubes he has. if he cant run 10's on pump gas he should shut the hood and slowly back away from the car. it not your fault his car is a heavy pig. the calculators are all wrong except one. the one that happens to match exactly what your car runs. ------------------

Once you start optimizing for the 1/8 mile, you start to learn that the average 1/4 miler is usually not running as low a gear ratio as they could. I was amazed at how the e.ts started dropping when lower gears and larger tires could be used.Lower rear ratios tend to drop the short end e.ts subsantially because it gives quicker acceleration and better torque multiplication. You will lose some MPH on the big end of the 1/4, simply because you use up most of the power band getting through the 1st half of the track. Sorry, just rambling on.. ------------------

I looked thru my old time slips last night. I had an 11.78@106, and several low 12's in the 104-106 range. I had one 11.80@108 with 1.70 60' time. Again, this was when my car wasn't legal to go below 12.00, so I was major sandbagging.------------------

Ok so must have you have provedme wrong yet again. Thats all part of learning isn't it ?
I can't see this guy sand bagging. Or hitting the brakes for anything short of a tree.
If I get the my motor done this winter. I'll get him to race me at Fallon in the 1/4 mile.Then we'll all for sure whats what. It still fun watching him get so upset when I told he couldn't run those times. The look on his face told me the whole story. The kinda of look that makes you want to call him to his word.------------------

SteveW, could you please explain that another way - as I don't follow you.... If you beat the chart as you're saying, then doesn't that mean your racecar has used all its available HP to get to the end very quickly, & is already slowing down before the strip? I'd guess most folks (including me) aren't getting ALL of the HP that they're making to the ground - thus, when we take our MPH and look on the chart, our ETs should be quicker. OK. But I don't see what's happening with your timeslips.... Ryan

The terminal speed can be down for several reasons,to much rear gear(the motor runs out of rpms before the finish line),converter efficiency,(the same effect) fuel bowls running low(not enough fuel volume at carb),and aerodynamics. This is generally speaking but i know our car suffered from the first three last year,the fourth is nothing to do about.Stock rules prohibits mods to the bodywork.
On a stick car the cluth may be slipping at the top end.

Ryan,Beating the chart tells me that the chart is not optimal performance, but rather average. The '66 launches and runs hard, low et's are made in the first 330' and a head wind is usually involved. SteveW

Steve, according to my HP calculator, you're producing close to 500 RWHP to run that e.t. through the 1/4, but to run 119 mph you only need about 420. Sounds like you're getting your best power down early in the run where it's needed the most! Good job! ------------------

Your et/mph numbers are more "normal" through the 1/4 than Steve's. If you want to find some hidden e.t. that might be left in the car, I would say it's in the gears or the convertor. Steve'66 has it figured out. Here's some little website calculators you can use:
