Time was not great, but Lydia got in the 11's, and 11 is 11.

Last year at LS Fest ran a 12.03 with 1.967 60' time. Couldn't even spin the tires. This rear I could spin the tires from a roll...LOL

Last year ran nearly a full tank of gas, and track was well prepped. This year I ran 1/4 tank to get weight off rear tires, but track was not well prepped. Also had to lanch from just off idle to take out driveline slack only as I lost my power brakes. Didn't get a chance to try adding fuel to see if the extra weight on rear wheels would help traction some. She's tail heavy as is, so any added fuel adds weight on rear tires.



360 RWHP, from GM LS3 376CI 480 HP rated Hot Cam crate engine.



3.55 Rear gear ratio. TCI 6X trans. Cricle D converter stalled at about stock RPM

Street tires, no DR's. No burnout before run, just staged and l left line with a nice slow reaction time.

Car as run with dirver weight after run 3564 LBs, without driver 3,339 LBs with less 1/4 tank of fuel.

Love to see some videos of Lydia scampering down the track??? :

Poorhouse,
I think I speak for many when I say we all enjoyed reading your build journey with Lydia.

To now read you're getting out there and using it as it was intended, and having a bunch of fun along the way is fabulous.
Life's too short, drive it's wheels off Mate.

Your 360 rwhp number is low. We talked about it several months ago. You are running times and speeds close to what a stock C6 Z06 with 450 rwhp traps. I suspect your rwhp is in the 420 range. It would be interesting to see what your car does on a Dynojet. Congrats on your 11.

Are you coming to the LS Shootout at Indy Raceway Park?

Mark,

Dyno can't make HP or TQ, it can only use mechanics and software to rate HP. Dynojet is the defacto standard used because there are more out there than any other dyno.

When Dynojet released their Winpep 7 software back in 1999-2000 engine builders and others called fowl because peope lost 20-30 HP due to changes in it to try and make numbers more realistic. Major difference between the two is the way Dyno jet factors precentage of drivetrain lost.

With Mustang Dyno I get percentage of drivetrain lost expected for 4L80E modified to ovdrive 1st to create 2nd gear, overdriving 3rd gear to create 4th gear which is a 1.18 ratio.

What most don't look at is transmission's I'm using 4th gear ratio of 1.18. Multiply 3.55 rear end by 1.18 and you have a 4.19 rear gear ratio rather than a 3.42 the Z06 ratio has to cover most if not all of the last of 1/4 mile. You have to remember there is whats call TQ ratio gear multiple.


Also if you look at cam the GM LS3 Hot Cam engine uses, I'm using TQ more so than HP because TQ is what gets you going. That cam is dead at 5600-5800 RPM. I'm running out air supply is what makes it look like it's pulling to 6500 RPM.

The LS7 in my 66 vert makes 25 more hp than the LS3 Hot Cam engine on same dyno, which is the same spread as HP rated at Crank by GM for both engines. At track even with it's 3.07 rear end it would smoke the 64 if it could hook up. 66 trans has a 1.13 ratio 4th gear that gives it effective 4th gear ratio of 3.46, but main reason it would smoke the 64 is it's weighs around 500 LBs less than the 64, plus the TQ band on the LS7 is broader than the LS3 HO.

Anyway I rather brag about my low HP numbers running with car with higher HP numbers based on Dyno manufacture software....

PS: Engine made 409 HP on Dynojet after slight tune that added the 9 to the 400 on 1st pull. That's 49 little ponies that make no difference in 1/4 mile time.....LOL

Poorhousenext

Thanks Ross. I have 6,747 showing on speedo right now, but the first 2 years I drove it, the speedo only read 19 MPH and 70 MPH so actual miles is more than what is showing.

Poorhousenext

I haven't thought about it. Put OCT 9-12 on my calender with reminders in case I can make it up there.

Donny Brass

Simply awesome............

Congrats on the effort, and I concur that we need video posted.

It's funny, the first time I got into the 12's it was with a 12.9990

What a great feeling that was.

Great Job

MarkC

I think we are on the same page. If you can find the time, do you have a thread on your 66. I like your toys. Thanks

Congratulations! An 11 is an 11!!

Poorhousenext

I agree, we are on the same page, it's just HP to weight and in my case a lot of luck.

The 66 build thread became neglected because of Lydia, but here is link to build.

Hey deceit MPH, but sick time. You put me through all your massive BS theory ten months ago for those results???? Very sad. I am surprised you posted it.

https://www.corvetteforum.com/forums...ding-62-a.html

Bring it on buddy. I am still up to a race. Why you LS guys can not pull a light is beyond me. (that one is for you Jeff )

Poorhousenext

No problem! I'll bring on if you'll run me with street tires. I know you would not attemp to run me without them slicks or DR's..LOL.

I have a heavier car and a lot less HP & TQ, plus I didn't even bother to try and heat the tires.

Give up those slicks or DR's run me pure street an I'm not sure with time you posted you could beat me, even with my terrible reactions times because I've haven't had in practice drag racing since 1967, plus I'd never even seen a PRO Tree Light before last year. Also have made only 7 runs to date.

You can use your Line Lock and I want even praticing launching with a Pro Tree....LOL At least I have a lot of room for improvement without having to increase HP/TQ or resort to slicks to run wth your Big Block...LOL

By the way, do you think it's possible to build a Mid Year that can run 10's on all motor with less than 400 RWHP on street tires? That less than 400 RWHP is as measured on a Mustang Dyno...LOL

I have a stock LS engine that makes less than 400 RWHP that can turn 7000 RPM but it's 427 CI and I rather try and do 10's with a 376 CI engine instead. Know were a project body is to put it in too.

65tripleblack

Congratulations!

I have to agree with Mark C on this one. Is your engine different from the LS3 installed in a stock C6 Corvette?

What size and brand are your "street tires"?

Poorhousenext

Car has Nitto555 295/45ZR18 112W on rear. Use them because they are 28.3" tall that when used with Nitto555 P245/45R17 95V on front that are 25.71" tall, is what gives the car it's stance. Nitto does not make the 295/45ZR18 tire size in their NT555R D.O.T.-Compliant Competition Drag Tires so their is no BS on my part like has been suggested in the past.

Picture of rear tire, You can go to link below to see they do not have the same tread pattern as the NT55R's...

http://www.nittotire.com/race-tires/...g-radial-tire/



The GM crate LS3 376CI 480HP Hot Cam engine used in car has a different cam from stock LS3 used in C6 Corvetes. Cam ups the HP 50 over the 430HP of stock LS3, but look at difference in TQ. I don't know about how some here think about TQ, but TQ is the key to this engine. The LS7 in my 66 has 505HP. It only has 25 more HP than the Hot Cam engine. Don't be fooled by that small difference in HP between the LS7 and Hot Cam LS3. No contest the LS7 makes power up to 6200 RPM and can pull to 7000RPM easily Vs the 5600-5800 of the LS3 HOT cam.

TQ = Acceleration, HP = Speed.

LS7 427CI 505HP GM Engine Dyno Sheet



Again I go back to rear gear ratio, that when coupled with Transmission gear ratios make a difference in acceleration between my car and that of a manual stock C6 or LS7 Z06.

vetrod62's car has a 1:1 4.30 ratio in 4th. I have a 3.55 1:1 ratio in 5th gear, but a 1.18 ratio 4th gear that = a 4.19 with the 3.55 rear gear that want shift to 5th until 132 MPH at full throttle. You can not rule out that advantage in helping me run both time and MPH. If vetrod62 were to change out his 4.30 rear gear to a 4.20 do you think his car would improve ET and MPH wise or turn lower ET and MPH?

I wish I had video so people could see that I drove around the water because of having street tires, when straight to start lined, staged, never revving the engine and left as soon as my mind, told me, "Hey Stupid the Light is Green, let off the brake and mash the throttle pedal."...LOL I looked at buying a video camara before I left to go to LS Fest, but decided it would be of little use as I only have one Friend and he doesn't like me so I was going to be their by myself with no one to video runs...

A street car on street tires, with no high stall TQ converter, under 400 NA RWHP, 3;55 rear gear and still got car in the 11's. While some here think that I should be ashame because car didn't go faster, all I can say is can say is you could do it ?

I have a car built to be driven. Going to drag strip just to see what I had built could do. Hell no, I'm not ashamed...LOL I'm grinning because it's so unbelievable how I could be so lucky...LOL

I live to drive for fun, while some live to drive a short trip to strip or tow, unload and race for fun... That one's for you Jim(vetrod62). Anytime your are willing to "Have car, Travel around 600 miles to meet me at a netural strip", I'm ready.....LOL

PS vetrod62: As they in California, "I'm just messing with you"....LOL

I'm happy to see you driving Lydia, How many of you have ever taken yours down the track?

Poorhouse, my hats off to you, big dollar car and 11's are very good for a street car.

Use it, abuse it and rebuild it.

No ****, What do you think, I just fell off the turnip wagon?? What we have been doing is Bench Racing. Seriously, You are over thinking every thing again. I am a hard core street racer.

Stop bitchen about the slicks. You are free to get you own. They are not that expensive. OK, now you bitch about how your rear is going to be broke. Boo Hoo. Well, that is on you as you did not build the car to perform with in the build you made.

Stop with the line Loc BS. The video posted on the earlier thread showed the Green 61 vette does not use the line loc. Been racing him for 45 years. We do the same 60 foots.


The tires you run are very good. learn how to use them.

If you heat your street tire, that is just dumb.

Ahhhh, yes it is possible to build a Mid Year that can run 10's on all motor with less than 400 RWHP on street tires? That less than 400 RWHP is as measured on a Mustang Dyno...

Yes, but it would take very talented, extremely dictated person to put that much effort into doing that. Not to many of them around. You shoot 5-6000 $$ to Donny, he could probably do it.

I live to drive for fun, while some live to drive a short trip to strip or tow, unload and race for fun... That one's for you Jim(vetrod62)



You have never driven, until racing on a bad track at 120 mph sliding sideways at full throttle through the lights. Always up for a race. Jim

PS, Lydia, give me a break, It is just a car!

65tripleblack

Your girly car name is sooooooo cute. I'm gonna rename tripleblack, "Shamiqua".

That motor of yours is really making about 425 - 435 RWHP on a DynoJet. Never heard of an engine making 360 RWHP and 480 flywheel HP, like yours. You must be using roofing tar for gear oil.

Those tires you're using are great tires, but they are not "street" tires for a normal C2. Yours have to be at least 10 inches wide, but mine are only 6 wide.

I run high 12's at 114 MPH.
