I won't have 450hp but will have a flat hp curve of around 410ish on a stock port motor. Pump gas 20psi.
Have the 16psi dyno sheet up already see sig.
Add about 10hp for every 1 psi increase.
Not the 450 big boys, but should have a nice 1/4 mile time with the hp and tq curve being so flat.
later guys,
Ralph

 

IT lives!

 

So not one person in here has a good 450rwhp 93octane pump gas run?

Jason is your car done being tuned? What did you make?

STEPHEN

 

I believe Vosko made those numbers. Though his drag times don't support it.

 

Here is my dyno # I post about a month ago, Jason put out the same # https://www.rx7club.com/forum/attach...postid=2067332

 

what the hell were you doing up at 7:30am dynoing?

 

worked all night working on the car, trying to get the car ready for a track event.

 

and how'd you do at the track? ET? MPH?

 

first pass clutch slip all the way down the track

nice dyno!! Mind if I ask what turbo you did this with? very impressive at only 15lbs boost!

 

T78 the boost was about 16lbs, large street ported pineapple motor 1600cc, 3row intercooler and all the other goodies.

 

Very nice indeed. Congrats!

 

Yea, I'd also like to see some people track times to back up thier dyno sheets.....not that I dont believe people I just want to see it for comparison sake. mph means a lot to me hehe

STEPHEN

 

vosko should have been putting up 125MPH + with his claimed dyno numbers.

 

Here is mine. It's 440 rwhp. This was at 17 psi on a Greddy T-78 on 93 octane pump gas:

 

what mph did you put up in the 1/8 or 1/4?

 

I'm at 440 @1bar on a T04R

I would scan it in, but my dyno chart is in the car, which is at the shop.

 

Yea, at least. I ran 125mph with a dyno of 412rwhp. Course I was heatsoaking on the dyno and getting good fresh air on the street.

Anyone that can lay down a 450rwhp dyno run should be able to trap at LEAST 125 but maybe as much as 130 if they dont have a full tank of gas and shift gears fast and clean.

STEPHEN

 

Amen. Too many correction factors floating around. No correction factors at the track.

 

Well look what the cat dragged in. Where have you been hiding.

 

i agree my traps should have been much higher but i changed lots of stuff also the map i was running when i made the 459rwhp pull. i also broke 3 differentials, 3 clutches, one diff casing, 3 transmissions, on the track i was running 305/40/16 M&H racemasters older than the car with low tire pressure so i could get some traction. that killed a few MPH off my time. 12.0 was ok.... but it should have been a low 11 had i not grenaded the tranny on the launch ! i'm gonna start over next year hopefully with a full race trans that won't break after one run and better tires and the car actually tuned the way its supposed to instead of my tuning it for 10.00 AFR

oh yeah this is video of me with the busted trans

first run bog and 12.0 @ 118. second run spun entire first gear and going into second and ran 12.4 @ 115... the car was making power. its kinda hard to drive a rx7 on the track with over 400rwhp. well the hardest part is not breaking the whole drivetrain

oh yeah did any of you guys watch my dyno video you can see black smoke gas coming from my exhaust haha

you can also hear and see it break up on the dyno with the video ah well that's life i'll just have to deal with it. my car is all smashed up now anyway

 

Here is Jason's dyno graph

 

I finally broke into the 500's. That run was at 19lbs of boost with a 11.0 A/F

Jason

 

i'm wondering also what is the corrections on those ? and how is it that smooth ? those graphs look TOO nice..... got any video of the cars on the dyno ?
