In-Car Video ~ Hyde's 12.05 @ 117.50 @ Summer Slam

[JekylandHyde]

This is an in-car video from Summer Slam.
This was just an open track run.

I "speed shifted" 3rd -> 4 on this run ... basically I shifted really fast while keeping the pedal floored. Notice how smooth Hyde seems on this shift compared to the others. Notice how little you here my BPV on that shift?

I've asked ya before, but I can't remember your answer, but anywas, what is the 60' and 330 times for your car? We race the car I have picture and the only track relatively close is only a 330 ft. track. Now the car isnt' set up to run the 1/4 (powerglyde trans, .513 rear end), but I'd just like to compare 330 times with ya.

Our best ever 60' is 1.46, and the best ever 330 is 4.25. I'm assuming that woudl come out to low 10s in the 1/4, but I dont really know. You seem to be the resident drag expert here, lol and I'm sure you've seen cars run similar 330 times to what ours does. If you od'nt care, coudl ya tell me what their 1/8th and 1/4 times are?

The last time we were at an 1/8th mile track the car ran 4.30 in the 330 and 6.71 in the 1/8th.

[JekylandHyde]

All of my slips are here:
http://www.jekylhyderacing.com/slips.htm
My 60's are around 1.7Xs and my 330's to be around 5.0X running high 11s and consistent 12.0Xs.

Not sure how your powerband and gearing compare to an MR2, but the fastest MR2 in the country hit a 1.52 in the 60' and a 4.327 in the 330 and managed a 10.276 @ 133.87

I hope that helps.

Thanks man. The cam in our car is supposed to make the most power between 1500-6500 RPMs, and it's a .630 lift roller cam.

Anyways, I don't think our car coudl make it through a 1/4 with the way it's set up (powerglyde trans., which is 2-spd auto, and a .513 gear). The last time we had it on an 1/8th it was very close to 7000 rpms at the end of the track.

I'd say with the times you have and the time you posted for the other car, ours would do atleast what that one did, but maybe a little better. I just wished there was a 1/4 track close to take it to and try!

[JekylandHyde]

Remember that the cars I posted are turbocharged, so they tend to get faster at the top of the track ... normally aspirated engines tend to not make the same amount of acceleration at the top compared to the bottom(from what I have witnessed)

[chevytrucks92]

Yeah, I understand that. The track where we run doesn't exactly hook up the best, and I assume that (by looking at your page and the tracks you listed) those do hook better. I do know our car is always a tenth faster everywhere (60' and 330') when we do take it to an 1/8th mile. It's got a bigger engine now then it did the last time we had it to an 1/8th (355 then, 406 now). Anyways, the 1.46 60' and 4.25 330 time woudl be like a 1.36 and 4.15 at the 1/8th mile track we go to (we usually go to Clay City, KY, but we have been to Bristol once). And the fastest 1/8th time we have was the 6.71 @ 101 mph (with the 355 engine). The 330 time for that pass was 4.30 (which would have been a 4.40 at our track, provided it was hooking like it usually does)

Saturday night, our track seemed to be off a tenth and a half, atleast judghing by some of our buddy's cars. We really don't know what our car should do right now becuase we have another new engine (we've had terrible luck this entire summer, this makes the 4th engine, the first 2 lost oil pressure, and hte last one had a cracked block in the lifter valley of all places). Our best time Saturday night was 4.434. We ran a total of 6 times, but the last two passes teh car spun terribly bad off the line, and spun even worse once it shifted into to high gear (he had to let completely off on the 5th run to avoid hitting the guard rail) And they haven't been giving us 60' times in over a month, been having troulbe out of the lights, and I think somebody actually hit them this weekend.

1st run: 4.439
2nd run: 4.447
3rd run: 4.449
4th run: dialed 4.43, run 4.434
5th run: dialed 4.42, run 4.685 (other car red lighted)
6th run: dialed 4.42, run 4.580 (needless to say we lost, lol)

One of our friends usually runs what we used to run (low 4.30s, and high 4.20s) and I think his best time was 4.49. So we figure the track was off atleast a tenth, maybe even a tenth and a half.

Track preparation makes a big difference.
Almost all of the tracks I go to are NHRA tracks ... but even they have "better" grip when they treat the track.
This is why I am only racing at National Events ... the track is always prepped then

[chevytrucks92]

Exactly. The conditions were almost perfect Saturday for making HP (it was warm, but the humidity was low), but the track just was pure junk. They have a dirt track right beside the strip, and they raced it Friday night, so this had dust all over the strip, plus it rained, plus you have the trophy class (street cars) that refuse to dodge any mud holes and well, you get the idea, lol.

Sometimes the track hooks really good though. They were glueing it all night, but it does no good to glue dirt!

I'd like to take our car to an 1/8th mile, and see what it would do. This engine doesn't sound as good as the others, but it is running pretty close to what they did. There is a difference in it however. the previous 3 engines this summer had 12.5:1 pistons (one had 13.5:1), and this one has 10:5.1 pistons, BUT the dip in the heads are filled up and so the shop that did the heads/engine says this motor will have the same compression as the others (he said probably 12.5:1).

You race that truck with all-terrains on it? If so, that and the 2spd powerglide alone say to me that you won't touch tens. If I am wrong though, please correct me because I don't know all of your setup.

[86MonteSS]

i think he is talkin about the 72 vega.......my buddy has an 85 regal w/350 13:1 pistons 202 heads....4:56 rear end gear with a turbo 350....he runs 11.20 average....his fastest is 11.04 at just over 120mph.......and just a quick question jekyl....how much money would you say you have invested in your motor to run what you do.....my friend with the regal has about 5k in the total car but thats about to be 7k after he get a 9 inch built....he keeps breaking the stock 7.5 ten bolt rear end

In my motor? $0.

Seriously ... my engine is 100% original, OEM engine with 199,870 miles

Everything I have done is strictly bolt-ons ... my investement in the car is over $12K .... but keep in mind I do SCCA Hill Climn races as well.
That being said I have lots of $$ wrapped up into suspension, handling, rims/tires ... lots of stuff.

Honestly not sure how much in just go fast goodies.

Lol, no, not the truck, lol.

The set up for the car is a flat top 406 SBC, with Dart Pro One Cast Iron heads, supposedly have 2.20 intake valves and 1.60 exhuast, but I would not swear to that becuase I have always thought 2.08s were as big as you could go for a small block, 750 Holley Proform carb, Victor Jr. intake, ported to match the heads (which are fully cut and ported), roller cam (dont know the specs for this one, other then its a smaller lift then .640), powerglyde tranny with .513 gears.

Where I race, it will run low 4.40s in 330 ft., with low 1.50 60 ft. times. All of this is at a poor hooking track with wore out slicks (31x14). At 330 ft, its turning 6000 rpms in high gear (shift at 6500 for this track), and leave the line at just 3400 rpms (to keep the tires as close to the ground as possible, and even at that RPM the left tire still comes up about 8 inches).

At any other track, you can subtract a tenth from those 330 times (make it low 4.30s at least, with mid 1.40s for 60 ft. times), and for that matter, when we put new slicks on the car this winter, it will run in the high 4.30s at the local 330 ft. track and high 1.40 60fts.

I'm positive the car will atlaest go 6.70s in the 1/8th at over 100 mph (probably 101-103 range), so I dont doubt it going in the 10s in the 1/4, even if it hits the high side chip (which would havde to be about 7500 for an 1/8th because it will turn 7000 rpms in an 1/8th, and 7000 is what we chip it at now).

So the way I figure it, if 1.70s 60 fts, and 4.80-5.ohs in the 330 will get ya in the 11s, then 1.40s 60 ft, and 4.30 330s will get ya in the 10s.

[jmrev]

thats crazy stuff man.

[victimizati0n]

it is called power shifting, not speed shifting.

Power shifting can also go to shifting w/o the clutch
