More low end power?

Postby mcrow » June 2nd, 2014, 3:59 pm

Anybody have some wisdom on how to make low end power on a low compression turbo car? My VRT has the low compression blues (8.5:1), and is pretty boggy from idle to 3K RPM. But when the turbo spools, it's fantastic. Am i just stuck with this dismal low end power as a sacrifice for big top end power?

Garrett t3/t4 turbo, 8.5:1 head spacer, 2.5'' turbo back exhaust, 20 psi of boost, stock cams, and c2 motorsports tune.

Making the jump to standalone will give you more control over the fuel and spark curves. Thus letting you tune the car for more low at the sacrifice of some top end.. the c2 chips are good for someone who was on a budget and doesn't know enough about forced induction. Next I'd look into another turbo. There's a lot of trick stuff out there now. The t3/t4 is kinda old tech. Not to say the old stuff doesn't get the job done, there's just better stuff or others that suit the jib better.. cams are another option too but I can't tell you anything about them being I don't know squat about cams.. lol. You can always give red_bull a pm and talk to him..

Cams will help for sure...
Is it the best bang for your buck though? That I don't know.

Luke, you'll have to let me know how your standalone works out. That's probably what i'll end up doing next year.

I probably won't do cams as I don't think the gains will be that noticeable and i do not want to mess around with the timing chains.

For now I think I will just try upgrading the exhaust to 3'' turbo back, and that should give me a little earlier turbo spool.

Depending on the stand alone you do not have to sacrifice top end power.

Cams if they help in the bottom hurt at the top, if they help at the top they hurt at the bottom. You may be able to find something that will help slightly all the way through but I do not think the gains would be worth the cost, this is the issue with static timed cams and the big bonus of variable timing.

options: variable turbo, quick spool valve (depending on current setup), nitrous, standalone, exhaust mods, compound turbo setup, one of those electric superchargers that guy with the golf was pushing on local forums, rev to the moon.
