321WHP 422WTQ dynojet SAE


Both setup identical except for turbo. Dom 1.5 10cm 2.4" vs stock VF39 both on meth. Its kinda apples to oranges (VF is maxed out, Dom 1.5 is just starting to wake up) as VF is 25psi tapering to 15psi and Dom 1.5 is solid 20 psi and it will need higher boost to shine but limited by fuel when tuning was done. Both are 3rd gear so spool is little late on both and I gain couple hundred RPMs later by changing cam timing on Dom 1.5 so dont get to caught up in later spool. VF39 tune made 322whp on dynojet SAE correction, havent dynoed Dom 1.5 yet. Both of these logs are uncorrected as I didnt record temps of VF run.

Major mods is GS 38mm EWG using 4port boost control, Perrin big maf with velocity stack, Invidia dp, ebay exhaust, stock long block with stock TGV, meth, lightweight pulley and ACT streetlight flywheel, GS PnP manifold, turbo inlet.

As you can see after 4800rpm the Dom 1.5 leaves the VF39

Sorry not trying to thread jack you there, just wanted to show comparision of VF39 to Dom 1.5
