SR Motorsports posted their specs on the GT4 kit. You can find it here:

http://www.srmotorsports.com/Mazda_R...o_Results.html

Their most recent dyno, although not on the website right now, was said to bring almost 40hp for $1949 (excluding labor costs). Compare this to the Canzoomer mod and their Mid Pipe, Hi flow cat w/ res and catback bringing around 35 hp for around $1500 (excluding labor costs).

I wish they would post their dyno result..

Something interesting too is that the PCM update was not included as part of GT4 as originally planned.

 

hmm..40 to the wheels with just i/e and pullies? i dont buy it, and i wont at $4000

 

damn 500 for intake

 

I like the pullies...

This is what I'd like on mine (if I ever get one):

pullies
flywheel
canzoomer Stage2
resonated midpipe
catback

header if they ever design a really good one

I wonder how much gains I could get... :D

 

Later today I will be installing the SR flywheel/ACT clutch. I already have the other stuff listed above except the ECU. I will wait and install nitrous first and see what is available for ECU's at that time. So far, with intake and full-length exhaust the car sounds great and pulls strong above 4K. I can't get anyone to race me though! I guess the local punks with cat-backs and undercarriage lighting know a real car when they see one(haha).

hmmm sounds fishy...

 

Whats fishy?

 

are there any sound clips to hear what the car sounds like with the GT-4 kit on?

 

heh, on the webpage it says..

The Project RX-8 picked up almost
40 horsepower on the dyno with the
GT-4 Kit !


.02$

 

And canzoomer is looking at 45+HP with a full stage2 setup as described. 25HP is stage1, but thats only 600 bucks.

 

Hm... CZ has not posted a dyno for the new stage 1, much less stage 2. Who knows what that 600 bucks is buying, 5 HP? 10 HP?.

I hate to keep pointing this out since I plan on buying the mod, but there is no way im paying cash for something that I have no idea what it does exactly; Especially with all the competition that is coming out now.

 

And here I was waiting for the ECU for the Auto! Boo!

If I replace a few more dinners with Skittles, I MAY be able to afford the GT-3 for Auto. lol.

 

I was using the broad estimates that have been mentioned before, and my updated stage1 was good for about that (22 to 27 on my g-tech), so close enough for me.

The old dyno was showing about the same gain. Seems well established to me it works by tuning the car properly.

 

don't know bout you guys but im waiting for more products to come out this year...
