Well, I finally dyno'd my GA67.

Stock ECU, RPS header, and Apexi FMIC.

I made 635 RWHP @ 25.5 psi and 530RWHP @ 17psi.

25.5 psi:

17 psi:

Those were peak boost levels. For some reason boost was dropping to 22psi from 25.5psi on the high boost runs. I approximate a 1.5psi drop on the low boost runs as well.

Hi,
Nice dyno runs, iam thinking of buying the GA67 with GTQ trim do you have any pics. of the install ? Did you buy a complete GA kit if you did was it easy to install ? If you have GA fuel system whats your opinion of that ?

Thnx in advance

Btw that torque number looks like you were running more than 17 PSI. Maybe it was 17 PSi at the end of the run?

'93 Black M6 Supra RPS CTC67H(.68 AR) AEM Tuned
(744WHP/662WTQ @ 30PSI-26PSI(boost drop at 6kRPMS), 114 octane, 533WHP/427WTQ at 18 PSI, 91 octane)
Best 1/4: 11.6 @ 126 2.0 60' on old setup at low boost.

Does the GA67 come with a 4 bolt or a V-flange?

I am seriously thinking of swapping my T-78 for a GA one.

Here is a pic of Sidwin's GA kit. They are very nice up close and quality.

Hey Sil,

I see that you got your car dyno already with the new setup. I also noticed that you made a lot of power since you broke the timing belt tensioner. When are you planning on getting it dyno again. I would like to get my AEM tuned by the guy who did your car. You can reach me at ht_mkiv@yahoo.com. Thanks

Hey Silv, does your porting and engine work make the torque readings low on low boost?
just wondering cause torque seems low on your runs on low boost?
Thanks
Dean
