3.5 DR750 build

[Chris@Rvengeperformance]

I mean you guys are saying that a larger displacement engine has greater exhaust flow for the SAME horsepower.

because....magic??

i don't remember the original thread, forest. i just remember that it had like a lower HP figure, but a TQ that was 100 or so higher. or maybe vice-versa. either way, the numbers didn't match up like one would have expected--and i think matt said he thought it was because of the 3.5L.

Internet mechanics....

Well I Dynoed it tonight on Ray Luna's new AWD Dynojet in El Paso.

21psi, pump gas/water meth tune
566whp
624 wtq

The car really has one hell of a power band, peek TQ comes in at ~4100rpm, and Peek HP at ~5100 rpm and the HP stays almost totally flat with almost no drop off to 7200rpm were I was ending the runs. Talk about a TQ monster!

Here is the funnest part, as you all know the car still has stock intercoolers on it, well the only fan thy had was a little house fan blowing at the front of the car ZERO air was going to the inercoolers. Meaning thy were doing nothing, it made this power for the most part non intercooled. I can only imagin how hot the air was going into the motor but you could have fried a egg on the IC's or IC piping after the pull.

Thy are suppose to E-mail me the Files , I'll post up the charts then.


I also have them E-mailing me a dyno chart from a DBB T67 supra that made 520 whp on there dyno (there old dyno record before last night) you should see that overlayed hahahaha, I have so much more usable power it's not even funny.

Edit Dyno chart added, here is a pic my buddy took of the screen, ya ya I know it ses White 240sx in the file, that's because thy did not open up a new folder for my car. Note take a look at that nearly totaly flat A/F, god I love the ARC-2

[Chris@Rvengeperformance]

Kids these days.

[IPD]

thanks, greg.

i was right, the HP figure is low on that run. it's flat, certainly, but not what was expected. and if memory serves, matt had initially pointed to flow at higher RPM's for the lower #.

nothing wrong with that, mind you. flat is much more "streetable" in my opinion.

[Chris@Rvengeperformance]

yeah no kidding, it is only 21 PSI. It is a pump/meth tune.

[R/T93]

566 low for 21 psi? You know these turbos can do like 32 psi....

[TurboSinceBirth]

All of the 600AWHP runs were 25-28 psi on stock and built motors when these first had numbers put out. Nobody ever pushed it hard on a stroker.

Gonna be a blast

Remind me of when Phillip said that the strokers would "drive like a tractor"
