It was really fast as you saw.

Slightly, just slightly faster than stock. Must have had some serious stickers somewhere to generate that kind of acceleration.

Nice run and thanks for posting the video; quite helpful.

Monza, who'd have guessed.

Speedy

What mods?

slam1918

I think it may be a chevy Vega.....the Monza would have left parts all the way down the track

My car is a NON-SPORT touring model. No wing, only 18 inch rims, it needed lsd so quaife was added.

AAM true dual 2.5 cbe
AAM 2.75 intakes (no insert, reqs tune)
AAM 350z test pipes
Z1 vqde35 headers
Motordyne M370 manifold (great for hpde, seems to limit drag racing)
Quaife LSD (bought for hpde events because i do alot)
Tune from Hills Garage on dyno dynamics 308.9 whp (balt, md)



I've no idea what that is on a dynojet.

One thing worth noting, previous best was 12.880 with aam hfc and no headers so make of that what you will.

I know this is not the section for this, but 308whp seems low for all that modification and $$. Maybe look into having someone else tune the car?

I was thinking the same.

NickTurnon

Some people are making 308whp with just intake, exhaust, and tune.

Seems crazy when BoomSpoon probably spent around $5k in mods (if my maths correct), and some people are getting there by spending $1500.

Sounds like he should've considered going supercharged to me

P.S His dyno chart says "re-tune $250" .. they retuned and still couldn't squeeze more out of that?

One thing: Dyno dynamics
Those dynos are know to read lower than any other, everyone talks about Mustang dynos reading low and be heartbreakers but go spend some time on a dyno dynamics and you will truly cry. For example, bone stock with my Z I put down 240whp on a dyno dynamics when everyone else was easily 15-25whp higher on a mustang dyno.

The "re-tune" note i scribbled on the dyno sheet is making note that it will cost $250 to retune if changes are needed.

In the next 2 months or so at next maintenance i was going to have aam do some dyno pulls on it so i have a dynjojet # with the hills garage tune. At this point 308 is meaningless for comparison unless yours was dyno'd at hills.

What does a stock car put down on their dyno?

No idea. Checking youtube yields results all over the place. Some say %10 lower than dynojet while others say add 15 whp to your result.

I prefer to just say my z on syreet tires runs 12.8 something, rather say 12.7 but maybe ill go a diet from 230 and take out the spare and go with less fuel, half tank this time. its cool to correlate the whp to quarter time for the z but it still depends on traction, weight, etc that it kinda doesnt matter

This is rudimentary as hell, but your trap speeds puts your whp in the 320-330 range.

I believe that's the same dyno that I did my baseline on.
I did it at 100 degrees and the car was heat soaked, oil temp was at 220+ and a small fan. Put down 252/222tq - Ran a 13.2 stock with street tires..

Our numbers will be off because of 7AT vs 6spd and other factors, but I just feel like you can have much better dyno #s and track #s - With those mods, you should easily hit 315 or so
