Hahn s20g true results
So tune wise, ecm controlled boost with a conservative boost ramp due to octane!!
24lbs steady 26 spike.
A mixture of 91/89 octane for results that people could see all around. I said I would and I delivered. People could easily do 25-26 steady and more lean and make more power... I put the 20g on for my fellow as owners that asked..
Mods that count:
I used aem cai, 20g, injen charge pipe hot side, tread stone lower with maf relocate, Zzp ic ( you heard right Zzp lol) Hahn catleas dp, magnaflow dp, ky cluth.
Dyno:
Dyno jet, outside temp 89 *, I span on dyno and those numbers were horrid. All pulls I span bad but still made great power for the octane and slow boost ramp. Straps are loose and fan speed is 20mph lol.....
So since I told you these things. What do you think power is? I have the dyno slip and I will post in a few hours.

As you can tell i tuned it rich, and i ramped the richness ( going from 12.6 midrange to 12.2 top top end!) For the conserve part of the tune!

here is the vid of how bad it was slipping. No matter what both lnfs that dynoed didnt hook.. So we got lower results. Time to get a better dyno place lol Btw numbers are horrible in this vid.. lol

For being a mix like that I'm impressed. The 20g is a well proven turbo in other platforms and in the LNF. Jeb, with one of our big turbo Sky's was pushing 450+ with his Sky and Hahn 20g setup. That's with a greater drivetrain loss as well and on E47. He will be making more here soon after some new goodies.

Lol it's my car . I put the 20 g on it... For purpose of people asking for real results . I put 89/91. In it to get a baseline number smaller then what actual numbers can be so you can see the honest potential around.... If I put. 93 in it, I'd make more of course. I didn't do e because doing e shows better results. But shows more potential because of the added timing and etc

I personally would like to see it run on a dyno dynamics or mustang dyno. I also believe in a car having an application for the power some are running. What is this for? Besides knowing that your a good tuner, will this be for drag? Track? Rally?

lol THIS setup is smaller then my original ful td06sh s20g with larger wheels.. I did this for the guys who wanted to see a baseline dyno of what the s20g would do on low boost (lowish) 24 -26. I did the octane because 50% of all gas stations dont have 93/92. And some dont even have 91. So i did the two of the mix. It hits full spool around 4200-4300 rpm ( its ramped in like this on purpose to for the octane reasoning) without the boost ramp i have it set at. I seen 3700-3800 average. Even showing these numbers prove that the hahn kit is well worth the money for s bolt on turbo!!. Thats the main reason i did it!

nice numbers man, and yet i hope people stop talking **** about something they havent even used. for been old tech like people say and ****, ths turbo really delivers and good a good tune and proper mods any cobalt can easily make 400whp. Hell i dynoed mines only on 19psi and it did 350whp

if i spool at say where it should (3800) journal with the 89 octane and the heat soak. I was getting little doses of kr, so with the slower ramp i was able to keep the timing and have it a little leaner in that part. (this was just a 1 day thing btw) Meaning i just did it to cshow capabilies. People will see more. This was just ment as a baseline
