@PRL Motorsports When you did the dyno testing for the big .86 a/r housing how far did you rev the car to? Essentially a lot of people are starting to notice that things can break easier having so much power down low, so thus putting the bigger turbo on shifting the power and torque to the right side. I’m just wondering how much more to the right it can go. Do you know the how far you can safely put the limiter/cutoff at?

Example: 8th gen civic si, safety can rev to 8k+ and makes power and keeps going.

Is this a possible power curve to achieve on this platform with the correct size turbocharger? I know upgraded valve train and possibly internals would be required for soemthing serious but like I said was just wondering if you had any insight of the limits for daily use.
My understanding is that these cars make the power down low and mid range and starts to fall up top, which is the point of these upgrades. We want to power to keep climbing.

We have been revving the car to 7200 RPM, you can see this in the dyno graphs. @KTuner had to do quite a bit of background coding to allow us to safely rev the car out this far. At this time we do not see a need to rev any farther as the stock cams seem to be out of efficiency and we are not sure how the valvetrain or rod bolts will take it. Though the future looks promising for internals for the 1.5T, these cars will never rev or flow like a K20; it's just how these engines were designed.

would the valves just be floating then? or is it just a camming issue?

 

[Hondanickx]

So why did you guys chose to use the .64 and .86 A/R Turbine instead of the .57 A/r ? Because of the V-band ?

She rips!! I love it!

Really? Idk it looked really slow tbh for 400whp, is it because of no traction?

Slow lol they were hitting probably past 100 in a really fast time and yeah street tires is no bueno lol

As of right now we are not experiencing any valve float issues. The engine/cams are out of efficiency where we're at.

Correct, the .57 A/R housing is not compatible for this reason.

I mean, that's how a full-weight, 400 horsepower FWD car on street tires moves haha. It's not exactly a "fast" "racecar," but it gets the job done.

So if I already have the Cobra Air Intake, Fp,Dp and intercooler and get the GTX3071 with .82 housing with everything else stock. Would that work and how much of a gain would I see?

Yes it will work, and you’ll see a impressive gain, run 93 octane if you can’t get E85 to do blends. Get a custom tune of course for max benefits and performance gains.

How much hp do you think I would get from this setup?

The current DP won't work a new one will be supplied with the new turbo kit. Also that turbo is good for 650whp+ lol you won't see that off the bat though you're going to be limited by fuel and internals. I'd question if the turbo would run out of it's efficiency range since fueling would need to be upgraded and at this time no one has released an upgrade yet. You'd also see a whole boatload of lag with that A/R housing on such a big turbo. Once more upgrades hit the market though sky is the limit that thing will be a monster! Haha

Ok thanks for the help

Np man I ordered the kit with a GTX2860R .64 a/r that turbo is still good for 450-475 and was recommended for stock internals motors ..I'll prob build it further down the road but should be plenty of fun! I'd assume on pump gas I'll see around 360-380 somewhere based on PRLs findings
