I'm looking to see if anyone has experience with the GT2, GT3 or GT4 performance packages available from SRMotorsports. Go to their website, and you will see something like +17, +28 and +37 horsepower for the three packages, respectively. They have some dyno print-outs to back it up. I've seen a few mentions in this forum that the RX8 just doesn't benefit that much (maybe a few HP gain) with adds like cold air intake, high-flow exhaust and midpipe, etc. All in all, 37 HP for about $2K sounds pretty good.

For the moment, I'm not looking for "yeah these guys are OK, but AEM (or someone else) is better" type comments. I see lots of other performance kit discussed, but I've not seen anything specific on SRMotorsports.

 

That package deal is something new. Atleast I've never seen that before on the website.

On a total guess. I think +20hp from the GT4 package could happen, that gives about 5hp to each mod. Dynos dont really mean much to me unless you test a car stock, then bolt every thing on, after it cools down and test it again all In the middle of the day, while the temp stays up.


You can see in here the best dyno of the day was 10hp less then a SR claims.

HEY, that's my dyno thread! I haven't had anything installed by them but after spending a whole day at their shop, I can tell you this....those guys REALLY know their stuff. (they were working on some RX-7's while I was there)

 

there full it ..

 

So, pardon the newbie questions, but if you install several mods, without doing an ECU chip upgrade, would there be as much benefit? Would you get more out of it by upgrading the fuel control as well? Can the existing ECU handle the new components, with a full memory reset?

Also, does anyone know of someone installing one of SRMotorsports packages, specifically, and what was the result?

 

Those packages will only give you small gains, maybe 6-10hp at max. If you really want to make hp just go FI.

 

Most your going to get is 12HP with the GT 4 kit.

It's all marketing hype.

 

If you're here *long enough* you should know that SRmotorsports is one of the most well known company that exaggerate like theres no tomorrow.After Vividracing I think.
