2000 camaro started as a 6 cyl. 5SPD. rebuilt a 2000 lq4 with btr stage 2 turbo cam. 1.685 long tube headers, deep motor sheet metal intake, 102mm throttle body, 42lb. Injectors, built th400, 3.42 gears. Made 373hp. On the dyno Friday. what do you guys think. #'s seemed kinda low to me even with the low compression and stock heads. Built for turbo but have to wait till next year

 

Looks about right through an unlocked torque converter.
What stall are you running?

 

Well they only make 300 to the tires stock and you have a converter that's likely killing off a little bit so I'd say you're near 100 over stock... that being said that isn't bad.

 

It's got a cheap 3200 stall needs a better convertor that I know

 

Btr stg2 turbo cam also isnt the most suited cam for an N/A motor so dont be too shocked

 

How does one tell when the convertor is causing power losses?

 

There's probably other ways but a couple I can think of is if you add power and the car doesn't get faster, or look at data and compare engine rpm to trans input shaft rpm above the stall speed to see how much slip there is "efficiency"... lower cost converters do tend to have lower efficiency. It's the only reason I can come up with for why my full weight bolt on car used to pull my buddies cammed lighter car. We would launch the same but once up on the stall and especially in longer gears I'd walk him. I had a $900 yank and he had a $400 tci.

Then there's also blowing through the converter where you add power and the converter fins roll or can't fully translate the power

 

Yea, thats about right.
