Whats up everyone this is for anyone looking at numbers for swaps from my personal experience.

My biggest reason in the first place to swap from a VMP Gen3 was the Belt system..... I wanted to be able to run 91 Pump (i know i know but i live in California.....) and not have to worry about the boost levels. Even on the 92mm 6rib the vmp made around 11-12psi that is the largest pulley they offer. When i was looking into a 8/10 rib conversion for the VMP it began to become annoying.... because the VMP system did not offer the Standard OD it was only 15%/25% OD system which would make the car E85 only.

I than started to look into Whipple Gen5 which even with the 10rib system offered a Standard OD and i would be able to go from 91 to E85 just by pulley/tune combo, which was great in my book.

I pulled the trigger and ordered the Gen5 with a 10rib and 150mm tb.

I was already expecting to lose TQ but i was okay with that to have a more manageable launch and roll car.

VMP GEN3 Setup
69MM Pulley
Twin 67 TB
Pmas Intake

RWHP: 904
RQTQ: 727
PSI: 17.57 -> logged by dyno

Whipple Gen5 Setup
3.25 Pulley
150MM TB
Whipple Intake

RWHP: 927
RWTQ: 750
PSI: 15.47 -> logged by boost box omega

I think my biggest take away is the amount of power it made at that boost level and how many more pulleys I can go until i max the Whipple out.

Who did the tuning on these combos?
Also, do you have better versions of the graphs? There’s a lot of detail missing.

I emailed them for email versions of the graphs, as i was suppose to get them right away....

Lund Tuned on both setups.


Wouldve been nice to see the VMP pulled up near 7500 like the whipple, looked close.
The VMP was pulled to 7500 and the Whipple was pulled to about 7350 so its either way the same.

Nvm. I thought the lower graph with the 910 and 927 pulls were both the VMP and Whipple overlapped
