Before and After dynos of a VF29?
I've been thinking about getting a new turbo. I know I want one of the smaller ones, like a VF24/28/29 or an SR30. Does anyone have any dynos on their stock turbo, and then their new turbo, so we can see the changes side by side?

Should be quite similar to Cobb Club spec dyno compared to Cobb RT spec dyno.
Crossover point was somewhere around 3500 RPM, I think (i.e. below that stock turbo was better, above the vf29 was better) While the RT has the uprated intercooler, it's still a reasonable comparison since the tuning should be at a roughly equivalent level. |

I'm interested too.
I would think it would be very similar to the more popular VF23, as they share compressors. However, it would spool slightly better and have a few less HP in the mid-top. Kevin |

Yeah, I have an idea for how the turbos compare to each other, but those don't give hard numbers. I've seen TurboXs's & Cobbs dynos, but those are for VF30 and SR30 I think. I assumed that the RT spec dyno was with the SR30 now that they've released the new turbos.

I don't think the dyno chart changed since they started using different turbos. Ask them, but I think that RT dyno on their site is still for a vf29.
