Also, I'm getting a little nervous as I think you guys have passed the stock transmission rated torque capacity :O Good luck.

what is the torque capacity on the manual?

John and Don - just to be clear I'm not accusing you of this. Most cars are nearest to 1:1 in 4th if I'm not mistaken. I would like to see 5th gear numbers but that may be asking a lot if you've been using 4th all along.

back to back dyno comparison on dynojet on 3rd vs 4th. Longer gears = more heat soak. Lesser powered cars do better on this 248c dyno because the pull isn't as long, so heat doesn't sink in. But slower cars have trouble spinning this roller to 110+mph, and the pulls take too long. But you can see the powerband is slightly affected, peak power IS NOT affected. And this is the story pull-after-pull. I did a 2nd gear pull and the vehicle lost power due to wheel spin though.



Don't worry about the gear, on a dynojet it isn't going to matter. Not peak power at least. You will spool the turbo quicker though in 5th. And the powerband will look more broad.

Well if you are looking for under the curve then we can't really measure everything exactly but peak doesn't seem affected. Thanks for sharing.

So we are currently at ~272whp/215wtq on 'unconfirmed' 8 psi.

So with a bit more tuning and a free flowing exhaust I don't see any reason why this car can't hit 300whp. And all on an untouched stock internals. Can't wait to see how everything holds up and what numbers are grinded out of 8psi.

You shoud start a new thread with this post and get it stickied!

I'm sure he meant more torque with the same peak whp. If that is the case, a restriction would have to be present. Either that, or have a boost spike in the mid-range.

like was mentioned earlier though, the eddy current dynos can be different because they don't measure acceleration of a fixed mass. But the longer the pull, the less peak power is produced... typically. Lots of variables between dynos. But on the Dynojet 248c, with added ballast to 1500whp+ capability, the results speak for themselves.

Glorious. You've made our 'sports car' a truly formidable sports car.

If the stock internals will hold up, I'm in.

Thanks again for being so transparent. My Accelerated Performance exhaust will be delivered tomorrow and then it's just a matter of time before the turbo joins it!

This still on factory injectors?

Ooooh I need to hear that exhaust. I'm going with the GReddy EVO3. Only because I asked what size the Accelerated Race exhaust was and not a single person answered.

I think it's 300 Nm. Since they're seeing calculated 220 ft-lb on the dyno, they should be a tad bit over at the crank.

What would cause you to believe that? This is practically a new transmission. They took one they already had and redesigned 80% of it. We've yet to learn it's limits as far as I know.

Here's the article I read this in. I'm just running my mouth based off this...

Rated torque capacity is just a guideline on what the OEMs can guarantee... You can usually push them to 150% capacity for a time on the track, or 300% for a weekend warrior that doesn't see a lot of abuse.

I took a transmission rated at 150tq and pushed 440tq through it for a few months before it grenaded. But it took to 350tq for years without issues. I'm sure 300wtq will do just fine for most. Keep a sprung clutch, and good gear oil. Should do just fine.

Stock injectors? Also this is a .86 vband housing?
