the car has mods as follows dc sports down pipe, hks hipower catback, nesei hard pipe kit, nesei fmic, k&n intake, hks 280s, arp studs, smc meth, 255 pump, ecutek, 20g, ported stock manifold, o2 housing, greddy boost controller, act street disc clutch. there is METH in the tank not half water half meth or dentured alky. its usin good meth.

 

Fine, but a 10:1 mixture won't cut it for best power. Retune the car and correct the AFR to familiar territory (e.g. ~11.5:1) by leaning the gasoline when the methanol is activated. Once you do that, you can slowly bring in ignition advance until you get knock counts, and that is all it will do.

A word of advice - don't expect BIG power numbers.

 

the car was runnin 10:1 in alot of areas and in certin areas u see fuel drop a little below 10:1 my cuzin is wondering who tuned ur car and wat do u think the car can make i can understand "dont expect big numbers" but ted getting a 20 g and using a bigger meth nozzle and makin 7 more hp and 10 pounds of trq over ur 16g tune does not sound acceptable to me.

 

You won't know what you have until you fix the problem of being too rich. But when you do, I doubt you're going to see what you expect out of that '20G'.

I had one of those 6-blade 20Gs like you have, and it was a big disappointment. I've never seen one do anything that couldn't be done with a 16G and 10.5 hotside. Your results may be different, but I seriously doubt it.

Now, go get your car properly tuned and let us know what happens.

 

ok ted u seem to have alot of knowledge and i thank u for helpin out can u answer this. is it better to be on a big meth nozzle or a small nozzle and if my cuzin puts the small nozzle back in wat fuel ratio should he tune for? i am not sure wat my cuzin will do but he has only seen very good results from everything he has done, and this 20g has crushed him and i swear he has gone into depression. can u name some 1 that tunes well around ga or is he gonna have to go to like ohio to burchur or ams?

 

The nozzle size of the meth injector doesn't change the target final AFR, which should be around 11.5:1 with the meth flowing. Just keep in mind that the larger the meth nozzle, the more gasoline that will have to be removed to get to 11.5:1.

The 6-blade 20G crushed me too, and it cost me a good deal of money to get to the painful truth. I was very disappointed in the false hype surrounding this turbo and I HIGHLY recommend AVOIDING this turbo altogether.

Finally, you don't need to make a long trip to Buschur or AMS to have your car competently tuned. Just keep in mind that tuning with meth requires someone who understands and has experience in doing it. Make a call to Andrew of Dyno4mance (www.dyno4mance.com), between ATL and Chattanooga. We've tuned quite a lot of meth cars over there (mine one of them) with great results, and he can advise you through this. He is very meticulous and experienced.

 

thx ted ur quick responce and answers have been a great help thx 4 answering my questions and thx guys 4 ur opnions this is the reason i come to evo M!!

 

You could also go see Doug at TopSpeed. He is a great tuner and is just outside of Atlanta IIRC. He has a dyno at his shop also.

 

If you are talking about Charles(ct9a gsr) he never had a 20G on his car. It was a stock turbo making 389whp 420trq.

I NEVER made 440whp with a 20G. I don't know who you got your facts from. I made 410whp and 377 trq with race gas and meth, but also with some issues.

The car made more power than the stock turbo all the way to redline. It felt good to me and I ran some decent times even though they were into a head wind.

Who is this by the way?

 

I could have sworn I answered this same exact thread in a different forum...

 

Not to mention, wasn't that on a built motor with AEM EMS? Not really your everyday setup. People expect huge gains with the 20g but don't realize how many 20g cars have HUGE, expensive mods as opposed to basic bolt-ons.

Nice new name. =P

 

Actually, when I had the 20G on it was still with stock motor and head.

 

Question that still hasn't been answered by the thread starter...is this a Buschur 20G-9 with the 5-blade WR wheel, or is this another vendor's 6 bladed 20G?

 

Oh, I thought you were EVOONYOASS who had an AEM EMS, 280s, Meth+C16, race FMIC, etc etc, when he installed his 20g-9. I didn't know there were 2 guys in Atlanta sponsored by Buschur with the same signature and both with 400+whp Buschur 20Gs, so I got confused.

 

I am EVOONYOASS. lol

I was still on stock motor and head back then still.
