Best way to know what power it's actually making is trap speed vs weight. People aren't hating, I've seen a high reading dyno here in oregon, a turbo d16a6 I tuned with a 14b put down 239whp on that on 9lbs lol, not a chance in hell, the car ran low 14s and trapped sub 100mph in a light ef.


I dont see a 87.2mm x81.5mm ever making that kind of torque na but hey maybe you got the golden goose man. Either way looks like a good setup. I have a set of crower stage 3s if you wanna trade those 2s out for them.


i know your thinking anyone saying the numbers aren't right is just a dick but the torque number is pretty much the tell all. Gsrs will usually make anywhere from 120 on the low end to about 145 torque unless you go big on the motor or just a plain old wizard with ****. Hp = tq x rpm /5252. Your hp is a calculation of torque so let's say your motor made something a little more realistic like 135ftlbs that would equate to 197whp with the same curve. Still a solid number.

like I said earlier dynos read different the real testing will be what it does at the track. My 85x89mm ls vtec made 231/155 tq and trapped 109-110 in my eg hatch.

I got my motor back from Graeme at Canadian cylinder head and on the dyno last week. Very happy with the results, on a mustang dyno I made 224whp on 91 octane on a 42 degree day. Going back in the spring on 94 when there’s some kms on the motor on hopefully a cooler day to shoot for 235-240whp.
