RK Engine Build and Upgraded Turbos

So... I am thinking of doing an engine build and upgrading turbos. I see RK Autowerks has done several builds. Is anyone running this build and can provide some color on power, reliability, first impressions. Any insight on working with this company / Razza. Is anyone aware of power numbers ? Would like to get any insights before moving forward. Thanks !

Hey guys, our forged F90 builds have similar power to the F10 builds we do.

Here's a dyno chart to reference a recent build. This car was a stage 3 build and is running our bolt on GTX3076R hybrid turbos.



As for reliability, we haven't heard any issues from our customers. Our forged S63s are set up to handle up to 1500 hp.

We'll have some photos and videos up in the next week or so from a car we're finishing up this week.

Startlinemotors on Instagram. Not a personal build but one with dragy and dyno's to have numbers proven. Videos in dragy too. 9.5 @ 146 MPH is their fastest time that I know of. With wheelspin

They have done their own stuff with Hybrid Turbos as well on that run, that's why they were able to trap so high 9.5@146mph run

Apparently two builds were recently completed according to their IG... anxious to see those 60-130s.

But I hear their 93 octane build can't even break the 6s...

I Hope I'm dead wrong

Get us some times please

I think Imran from evolve is getting his built later this month .. so I'm sure his times are forthcoming

Ja
