EVOCRAZY: A built engine doesn't really give you more power, just the reliability to run more boost. Maybe I'm a sissy running 22 psi, but I don't trust running more boost on pump gas for road course use.

Ken: No datalogs right now.. I haven't received them yet from the tuner.

VividRacing: 2.0L

I'm more than willing to take donations on more aggressive cams

I asked this cause I made about the same hp and more tq than you on stock head,block HKS 272's and stock ecu on pump gas, on the same dyno. Ive been around I know what a built motor does, I was assuming you had a ported head ect.

naw, when you're beating on a car as much as these timeattacks require, being conservative with the tune is pretty key. HEAT IS MURDER

the tq curve looks very similar to that of the magical "twin scroll", but with much less torque decline in the topend and half the price

can't wait to see the logs Bob

Also what do you hit full boost by on the road?

0.60 AR on the compressor
0.63 AR on the turbine

I don't have any logs with boost on the road, but it's about the same as the dyno graph - 4200 rpm or so.

Exactly, Mines a lot bigger.

Mines in my Sig. PSI was 22-23psi

How much torque did yours make and at what RPM? I'd like to see your dyno chart. Mine looks almost identical to the AMS GT3076R 2.0L dyno chart with a AEM EMS, so I don't have any reason to think there's anything significantly wrong with the torque output.

Another possible difference is the BR block maybe lower in compression, which would definitely hurt torque.

The torque is low because he has a aem truboost boost controller. Their is no gain setting on this bc, like the greddy profecb controller! So the boost is only going to 16 to 18 psi by 5k and climbing to 22 to 23 at the top of the gear! With a better boost controller this car would make alot more torque. I would say around 50ftlbs more!

Looks great but the numbers do seem a bit low for that set-up on that dyno. IDK though.

I think it looks like a killer powerband. But I'd love to see a log if you get a chance Bob

The powerband is sweet. I'm not as worried about peak numbers as the usable power band.

My tuner said he deleted the logs... I'm going to take it back to the dyno after I change the WG spring and do a bit more street tuning. Hoping the stiffer WG spring will help spoolup a bit. I'll definitely get some logs myself next time.
