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. [attachment=33148:attachment] 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. |

Sicc Horsepower! So who did your swap??? I am in minnesota and that is pretty much what I am plannign on doing.. was contemplating a 20b but I htink 13b will do... what $$$$ value did it take fo ryou... I have an 85 GSL-SE... |
Way to go DF.Nice numbers.Now throw the widebody on it and you'll have both show and go. https://www.nopistons.com/forums/pub...IR#>/bling.gif

Back then, we couldn't raise the boost higher than 14psi, otherwise the ignition was breaking up. When we returned, the problem persisted - until we found out the dyno ignition pick up wire was actually causing the cross-fire. Crap! Well, once we eliminated the dyno RPM signal wire, we were able to increase the boost: Numbers are: 336 at 9 psi (pump gas) 409 at 14 psi (pump gas) xxx at 18 psi (pump gas) XXX at 21 psi (C-16) The car: 1985 RX-7 GSL-SE Haltech E6K -Tuned by Crispeed 63-1 Turbo Ford 8.8 Rear End (very heavy!) Isuzu NPR Intercooler (Large) 720's & 1600's Aeromotive 1000 Here's the video of it all: High Resolution (89 megs) right click, and Save-As <-Thanks Vosko! Low Resolution (Streetfire) <-56K Only (should be working soon) Let me know what you think. I'll post a full dyno sheet soon. The engine is definately capable of more power - We just ran out of wastegate spring. We could't run more than 20psi. Even with the Profec B set all the way. I have a 9lb spring in the Wastegate, and really should be runninng a 14+lb spring to enable higher boost. It's all good though, and I am verrry happy with the performance, Especially from a relatively small turbo - deisgned for street use, quick spooling. Once again - Thanks Chris. |
Is this the car I have seen video of taking down the 350Z and then the guys in the 350 were claiming the rx7 was spraying?
|
is that a streetport on an otherwise stock motor? if so, you're a badass. took me a while (after watching the dyno vid.) to figure out that's 11k rpm you're hitting. i'm supremely jealous...
|
wondering the same too, is that stock port?
those numbers seem doable on stock port. ive seen 60-1's do that with 4psi more, so 63-1 could manage i bet |
