When I went with the 3.47 jackshaft and 3.00 sc pulley and turbo guard screen it made 16.4.

All confirmed on the dyno.

Making a little less than 11 is the norm with the 9 lb pulley and this kit on over a hundred kits. How 11.6 on the 8lb is happening is a mystery.

I would suspect it is because of where and how it is being measured.

No mystery at all, the larger charger pipe and less restrictive intercooler in our kit allow for the increase in boost.

We have done a number of testing with intercooler cores and sizes and have found different cores will develop different restrictions and pressure losses throughout a system.

What I mean by this is it depends where the map sensor or boost sensor is located. I read somewhere that the best place to pull boost pressure from is before the throttle bodies on the intake side. It is a more stable reading. If you pull it from the intake itself, it is not very stable. So, You guys are pulling the readings from two different places. That is why they are different.

Nobody is pulling it from pre throttle body. All of these are measured at the manifold. Including the one in question.

LOL, you’re including your self especially, right? With statements like

“So, You guys are pulling the readings from two different places. That is why they are different.” When literally no one is doing that.

Could it be from their set up having a bigger Y-Pipe and FMIC as opposed to your kit Topz? I don't know for sure, but was told that they run a bigger FMIC and that their Y-pipe is a full 3"

I believe the maf pipes on both topgunz's and soho's are 2.75 inches.

Nah man, I’m cool! But if you’re gonna laugh and make incorrect statements about people here and incorrect statements of your own, and then of all things, accuse everyone else of “making a mess” expect to get called on it.

DUSHER · 12-23-2019, 12:43 AM

no offense to anyone but you guys should move this to another thread maybe?

Senna-F1 · 12-23-2019, 12:44 AM

did you notice I mentioned that 3 times already? Can’t help they didn’t listen.

Can I ask again, is this a tune to show its potential, or will your customer also primarily run this on the streets?

Thanks
