I have been researching this all over and haven't seemed to find any information on this type of upgrade. I currently have a brand new MHI 18k unported about to be installed as soon as my last part arrives (MAP investment manifold) and reached out to someone who said they can convert my 18k to 3076 hybrid, keep the same spool characteristics and gain more power. It'll utilize an upgraded 7 blade extended tip wheel and should make around 450-470ish to the wheels. I have a completely stock SST with no cooling mods since it's specifically a daily driver and go WOT maybe once every few weeks if I'm in the mood. Since this is my daily, I want full spool around 4000 rpms and the 18k fit the bill. Has anyone heard of this or has any info if I should go through it and gain more power while retaining same spool? Great reviews from the builder, but I can't find anything about this conversion. This will all be on pump gas only unfortunately so if I can add this much power, thinking it might be worth it.

 

Do not do this. That wheel, those claims, just no.

 

The 18k will make 450-470 at the wheels on E85.

That being said, your SST will be on borrowed time at that power level.
