Dynamometer Results & Comparisons - 441ci LSX Twin Turbo new #'s! Precision 67 CEA vs Turbonetics 70
01-07-2012, 07:10 PM
Heres my new graph showing Precision 6766 CEA billet, ball bearing with .68 a/r's vs Turbonetics TC7068 cast, journal bearing with .81's a/r's. We did not change anything but turbos and the air/fuel and did not touch the timing. Its still low like it was when we tuned it in 110 degrees out side. The Precision graph is on 21lbs and the turbonetics is on 17.5lbs. when we compared 10lbs vs 10lbs it was 695rwhp vs 790rwhp. Each time we turned it up it would love it. 17.5lbs vs 17.5lbs is 916rwhp vs 1030rwhp. i picked up 250rwhp and 250-300rwtq under the curve and from the get go i picked up 150-200rwhp and 150-200rwtq off throttle.

That is a substantial difference! Worth every penny to make the change.

with the old turbos it would peak around 6000 and fall off at 6300 RPM but with the new turbos it looks like if we stayed in it it would of kept climbing to 6800-7000 RPM. why is that?
Turbine design, compressor wheel design, hard to say exactly.

hows the tranny hold? and im sure it s insane but can you really use 1000 at the wheels? like i mean when do you get to have fun? in my haed under 120 it wont hook and how many times can you go 200 LOL before you get caught or something happens? not tryin to be a dick im serious i wanna add more hp to my car but even 500 at the wheels is dangerous it hits 100 so fast im just waitin for the car to get taken away
