MAPerformance: Ultimate R&D Thread | Air, Fuel, & Turbo Upgrades

[BigCatDan]

The bigger the turbo, the longer the lag. On the 5858 with big exhaust housing (.82A/R) full boost (24.5psi) is 3,900rpm's starting the pull at 2,000rpms. The stock turbo full spool was 3,000rpms (22psi). So there is a 900rpm difference between the two. The 900rpm added spool up time is worth power and torque to redline.

Ok so I can kinda understand it, for real world driving, this means that the car will be slightly slower off the line, but much faster once the boost kicks in? I don't mean to Hijack this thread, so ill let Adam get back to work, after this. Thanks again Adam!

What are the pros/cons of journal bearing vs. ball bearing?

Cost vs performance. Ball bearing turbos spool faster but cost more.

If my memory serves me right, I remember Adam saying that a ball bearing turbo spools 400 rpm faster than journal bearing turbo.

Exactly, at MAX. Some BB turbo's spool within ~100rpm of JB.

Adam, are you able to offer pricing on both and let people choose BB vs JB? For those with budget vs those with deep pockets?

The website listing will have an option for both JB and BB turbo's.

I can't wait for this kit. I'm holding off on CAI, DP, Charge pipe kit because of this turbo kit. Feigning like a crack head for FMIC to ship and this turbo kit

Any idea when these turbo kits will be on sale?

Damn, that looks like a nice jump, nice job. Did I miss it, still on stock internals?

 

[Bomicino]

Hopefully that 5862 gets both curves comfortably into the 400s!
