mods



its a 6 port NA s4 block with about 200K miles on it now.



im using s4 t2 manifolds port matched to fit the block, and an s5 turbocharger. i have an rtek 1.7 with 720cc secondarys and a walbro 255 pump. 3" exhaust and TID mod, and a SAFC.

Post the AFR sheet.



Those dyno dynamics read lower than most dynos I have been told also..

HUH, no response. I will have to pester him for you. Dyno dynamics are great for tuning bad if you want to get numbers. 15-20% less is what I was told.

Wheres that little blip coming from at 4k?

i belive the blip in teh graph at 4K is a boost spike from my home depot boost controllor! yeah i need to get the A/F sheet i hung the graph up in my friends garage ill have to take it and scan it

guys its the otherway round,DYNOJETS are 20% approx hi wehn compared to hp vs maths vs mph and times vs dyno dynamics.



good work on the car mate keep it up
