and in another dyno untuned it did 321 hp 316 tq without the :
Holley air filter,Bo White TB , TB Bypass,3" cutout,3" Y Pipe

then after installing them did 353 hp 353 tq on the same dyno.

 

when i was just cammed(tr224/112) in an A4 I put down 349rwhp 355rwt(ls6manifold).I put 350rwhp one time in better weather,but we got about the same power out of that cam.I now have TSP stage 2.5 5.3 heads and a ported fast90/90 and put down 417rwhp 407rwt.still have the same cam

 

you`ve had a very good gain was your cam the 58x lift or the 56x lift? and if you see my graph it only makes power to 6000-6100 rpm where did you peak and how was the graph past 6k?
used 918`s with the prc heads or shimmed duals?

 

I made 351hp and 341 tq with the tr224 and a ss4000 stall.

 

Tr224/224 563/563 112
I used 918 when i was just cammed,but my heads came with duals. I may go with a slightly larger cam ,but I'm afraid of losing tourque i have with this one.I may go with a reverse split (mti x1).Not sure yet though

 

stock 806 heads here but i am a m6 395/381
