The car currently makes 390rwhp on a 224R cam and most of the bolt ons with a best ET of 12.30. What kind of power/ET gain can be expected with some stage 2.5 5.3l heads. Also, I understand that this setup will raise compression to 10.75:1, so how will this affect the car if a 100 shot(TNT wet kit) is sprayed ontop of this, versus stock heads. If anyone has this setup, feedback please!

I have a f13 cam and when I went to those heads I went from 373 to 411rwhp with a A4 and 3800 converter as far as ET I wont know till the track opens

it should react well to the jug.the slightly higher cr won't have much of an efect on the bottle but it will give you a slightly higher dcr which will help bottom end grunt if the ported heads don't make you lose alittle with their bigger runners.

I can't think of a cam that doesnt react to nitrous in that doseage.

100 shot will act about the same on any cam. Doesnt matter if it is a tradional or reverse split, big or little cam.

Heads are gonna add power regardless. Higher compression is usually better for nitrous. The 5.3 heads will add anywhere from 25-40rwhp. Also plays a role in how much your cam is using their abilities.

I have Tr224/112 cam with those heads in an A4.Iput down 411 rwhp 400ft so far.The reason i say so far is that the numbers were still climbing then bang!!!My driveshaft whent out.Before the heads and fast intake I was just cammed with an ls6intake and put down 348rwhp,so with the heads and fast it gave a 62rwhp SO FAR.We'll see what it does when we finish the tune.You could go to the dynamometer section and look for my post/thread"A4 TR224/112 TSPstage2.5 5.3l fast 90/90" it has my dyno graph.Hope this helps
