Buick Grand National Turbo swap yields huge gains 

@1:32... Epic!

Beatifull....nice work

Great content. 👍🏻

For better “snap” cruising around you can add timing below 3k and not under boost. It will get up on boost faster. Bad ass car by the way!

Crazy move on the dyno curve with the new turbo. That's gonna feel great on the street! What's the combo?

Awesome information. Do HPT make a good turbo to bolt to stock manifolds??

Impressive for a V-6 but you say its a street car will you ever be able stay full throttle because i see you breaking tires free before getting into power band

This is effin insane ! Who built the bottom end ?

What rearend do you have now

Good info and comparison.. I just got the hpt 6466 and love it! @hptturbohploilafis
