ACE CS400 Dyno's Please

Not gonna lie. No cats on a stock muffler will sound like crap, because the muffler will rattle.

Goes for any catless header.

It's at Church; the before dynos are the same as any other FRS/BRZ tuned there, there are hundreds of dynos scattered throughout the forums. A CARB JRSC should put down approximately 245-255whp on ACN91.

Here's the CSG BRZ on HBP (9% more boost), and a A/350 (non-ceramic) on E70.

Not shown: CSG BRZ on HBP and A/350 (non-ceramic) on ACN91 puts down approximately 335whp.



For reference, here's a stock 2105 ACN91 vs A/350 ACN91 vs A/350 E70



and my 2017, stock, on VP101

Thanks Mike.

I'm especially interested in seeing what the torque curve looks like with a CS 400, the JRSC with stock pulley or E-Force with stock pulley, and 91 octane gas.

Actually, I'd love to see a comparison with both superchargers, but that's probably asking a bit much.

I'm running the stock exhaust system with just the CS400. There's some very minor rattle, but it seems the OEM resonator and second cat are enough to tame things down.

With the OEM front pipe, the rattle is tamed down; you should try a catless front and you'll barf at the noise.

Seriously. But that's what prompted development of some catback options

Nobody locally has that combo; everyone here goes 350 after seeing the results =\

Yeah, I'm gathering that. I was under the impression that the top end difference was minimal between the 400 and the 350, and considering the price difference and that I spend very little time in the very upper ranges of the rpm band already, I thought the 400 was a good choice. I still think it is, for me, but it's hard to figure out what to set as my next goal.

I probably doesn't matter, really. With duty/taxes/shipping/exchange rate, an FI kit is pushing very close to $10K CAD. It'll be a while before I have that much cash just burning a hole in my pocket.

Yeah, I heard one video. It was more than enough to tell me I don't want that setup.

From what I've seen unless you're really wringing this motor out non stop the 400 seems to be a great compromise. Looks like the 400 gives a bit more down low torque but gives up just a little high rpm peak HP.


If it fits fine and is the "torque monster" it is marketed as, plus the lower price point.....


Is this not the case?

It really depends on what you're doing with the car. Some people are more comfortable redlining everywhere than others.

Mostly street driving, edelbrock SC, and some autoX mixed in.... although you have to redline the car to get performance out of it anyways.

That tells me you're better suited for the A/350. If you had said everything but that, then I'd say the CS/400 is a better match for you.

Thanks guys please post more.

I'm staying NA with CS400
