1985 RX-7 GSL-SE
13BRE "Cosmo" Two rotor
93 Pump Fuel / Low Boost Setting (14 PSI)
Haltech E6K / 63-1 Turbo
Ford 8.8 Rear End (much heavier, with more drivetrain loss)
Nasty, Hot Conditions - 100 degrees+
408 RWHP at 14 PSI

Crispeed Tuned.



Don't go by the A/F numbers on the Sheet, the Dyno's wideband was off by .75 or more +/-.

We were getting bad ignition readings over 14PSI, so we couldn't run anymore boost. Might have a bad CAS. Will look into it this week.

The car did 340 at 9 PSI (Wastegate spring) and 408 at 14PSI. Looking forward to 17 and 19 PSI on pump gas. Then go for broke on Race Fuel.

I am verrrrry happy with the Turbo. The boost comes on nice and quick,
with no lag. Pulls like a freight train. The drag radials are no match for traction.

BIIIIG Difference in drivability over the Holley Blow-Through setup I previously had. Not to mention, more power under the curve.

I am in love all over again.

Thanks Cris.

 

SaaWeeet!!!!!!

 

damn man.. how much $ did that run you? selling the old setup by any chance? haha

 

Nice.

 

woohoo those are some nice numbers.
good job

 

Wow. Gotta love it.

 

Pix of the car?

 

whens the next epic kill video coming out?

 

Not too soon. Still got some more tuning to go, and work on swapping some smaller rear brakes into the car.

Hopefully in a month or two.

 

You = my hero.

 

Nice!!!!

car ****

 

very nice! congrats

how much hp gain did the efi have over the holley at the same boost level?
i know what you mean about driveability, you cant beat efi with a good tuner behind the keyboard!

 

It's not a real comparison.
The Ford 8.8 with the 9" ends, and Auborn Diff
are much heavier and more difficult to move that the
Stock GSL-SE Rear.

I've seen guys losing 50 WHP with just that
change alone.

But, for Pete's sake:

Last time:
Ported Engine:
Holley = 385 at 15 PSI (Stock Rear End)
Haltech = 408 at 14 PSI (Ford 8.8 Rear End)
Haltech = 340 at 9 PSI

Based on this, Minimim of 23 HP, but I'd say at least 40-45.
Compare it at 9 PSI compared to the Holley and stock port.
It's a difference of 70HP, even with the new Rear.

For Reference:

Originally:
Stock Ported Engine:
Stock GSL-SE Rear End.

Holley = 270 at 9 PSI
Holley = 315 at 12 PSI
Holley = 370 at 17 PSI

I am really impressed with the car now. Feels like OEM.
and aboslutely no bogging, and no gas "stink" on everything.

Cris is really, really talented - especially on the keyboard.

 

what made you decide to swap the rear-end? how did the stocker hold up?


oh btw pics of the new set-up?

 

very very very nice

let's see an FD and/or supra kill vids in the future

Here are some pics of his car. Very clean.

 

congratulations. 408 while losing 50 to 70 through the rear is still very impressive.

i remember when the turbo inhabited Kramer's passenger seat.

lesson: patience pays ...

Get that sucker to the track..10's should be easy.

Holy ****. You are a god. Your holley blowthrough is what tempted me to do similar in my car, but this is just amazing. I'm still goin to have to keep my plans on the carb since I don't have the money for a high dollar computer and the tuning that goes with it. Hell, I don't even have the money to do anything to my car as it is, and I haven't even began to get the parts together. But as stated before, patience pays off in the end.
