I'll post up pics of my dyno chart once i get home from school. In the meantime though, i have an SR20DET redtop with 3" turbo back exhaust, large core FMIC, OEM T25, OEM injectors, OEM MAF, 1.2mm headgasket, Walbro 255 fuel pump, Z32 fuel filter, HKS step 2 cams and adjustable gears, SAFC II, and an AVC-R.

At stock boost (.5bar) w/the AFC tuned the car laid down 209whp and 199wtq on a Dynojet with A/F ratios of mid 11s across the board with a very smooth power curve. I hope to be able to tune the car for high boost in the upcoming week.

During the course of the summer I hope to get some engine management, upgrade the remainder of the fuel system, and upgrade the turbo and manifold all for 350-400whp.

Late,
Daniel

Did you install them just to see what they do because stock cams work better with t25's than upgraded cams.

i get outta class at 4:00.....i'll post up the charts once i get home

no i didn't install the cams. the cams, gears, and head gasket were already installed on the engine in the clip i ordered. i know the cams are a little overkill at the moment, but they'll be just right when i upgrade the last few parts to make more power :rawk: besides, the lopey idle sounds great :cool:

Ditto. Only HKS stage one cams dont require a valve spring upgrade. After that, you run into float. Curious if you just didnt list it, or you dont know if you have them

Funny you say that... I remember driving an sr20det with upgraded cams (unknown) and a t25 and it was super beneficial to it in everyway possible in the powerband.

i have an iMac and the dyno charts i was sent from the shop won't open :(

they're in *.drf format, and the Winpep7 program (dyno program) isn't available for Mac. anybody have any suggestions as to how I can get these files open so I can convert them into a *.jpg format and post them up???
