Figured I'd post some results. This is the highest I can get out of the hta68 on DB's dyno. Thanks to Nuke and TDagen for checking it out over on Nasioc, giving me input throughout the issues. Still trying to diagnose what is going on with losing power. It seems to be narrowed down to just to small of a hotside. Hopefully that's the issue. Open to thoughts.
Grimmspeed header with highflow cat and uppipe. I think tq is low since it's a 2.0 and the cams. I think the cams just kill tq, but that's just a guess. I'm sure people that have more experience with them can chime in.
Wow, so you're running 27-28psi right to redline? Is the hta68 still efficient at that level or is it a flamethrower?
Well, take a look at torque fall of dramatically after about 6600. I like the high redline, but you're not really seeing good power that high. Anyway, very nice setup, regardless. E85 is a beast
I'm going with flamethrower on this one. FP lists it being effecient up from 17-25 psi. Thanks bullwinkle. It is fun up to 6600, that's for sure. This is just proof I need to go bigger!
Rpm is one, he's wasn't going to 8k (I think he is still on stock engine and heads). To go with that, no headwork. I just don't think this turbo can push enough air for my setup. Well, that's what I hope at least.
I wouldn't be so sure about that, Evo III 16Gs are even less efficient, and there are plenty of people running 30+ lbs/boost on those. On other engines 272's help high end, while hurting torque and low end. I wonder if the curve looks so different compared to the other car running the 68hta because of a Dyno Dynamics being a load type dyno and the dynojet not being able to load? These are great numbers though!!
Nice numbers, I should convert to E85 after seeing this results :yumyum:. Too bad I have to drive it in the winter too.
Why is this a problem for you? E85 becomes E70 in winter (to help fight the cold). I'm running that and its going great so far.
Many people experience hard starting in the cold weather, especially if the car is parked outside regularly.
This may be a dumb question, but tune at the beginning of the tank? Is there that much variance?:???: Do folks do that? I'm thinking that's a little too much for me...
Sick..from Mankato? My folks live there, might have to check that behemoth out next time I'm down there.
