turbo talk, again [Help choosing turbo]

[dsm-onster]

No, I dont think I've out grown it. But with my new setup, I can take better advantage of a different turbo. I was considereing water injection, but it looks like a pain and race gas does the same thing anyways and is a bit safer I think, maybe Im wrong.

On a stock unported head and stock intake manifold, using the 60-1 is pretty much pointless IMO, but it definiately made more hp than the 50 trim.

Hmmm, wouldn't cams help alot still and give you the gains worthy of keeping a 60-1?

I don't know how filling a container with washer fluid at every other fillup is a pain . What's a pain is the inflated gas prices that have affected race gas prices. But that's just me. Race gas is safer though. If you're WI quites you'll be SOL. Filter your water and pick a good pump and a SIMPLE control system.

what makes you say the 60-1 is bad on pump gas, thats what im looking for, a pump gas turbo...

 

[BrokenTsi]

I got hks 272's. 60-1 does make some serious power, but not until about 28psi.

If you were lookin for a pump gas turbo, I would suggest the gt30r. Its good on pump, and also loves race gas.

Dont get me wrong, 60-1 is a real nice turbo, I may even keep it because it was cheap and flows 60lbs/min. But I get bored with turbos real fast and i always want to try something new, .

Maybe i'll experiment with water injection and see how it pans out.

60-1 just isn't efficient on pump gas, you can make more power on pump on a 50 trim or something similar. I know at 20psi, my 50 trim felt much faster. But anything after that, 60-1 just felt like it had WAY more top end power according to the butt dyno.

 

[tstkl]

then maybe i will go back to the 50 or 57 trim... makes a little more sense since going from a 60-1 to a g35r (what i might end up with in the long run) would be such a smaller jump in size... and since i wont have any internal or head mods it does make a lot more sense. mmmm the beloved 50 trim, a turbo i though i would NEVER get, (although i dont know why, young ignorace i guess) anyone else think i should stick with a 50/57 trim over a 60-1?

 

[v2ner]

BrokenTsi is correct. that turbo does not wake up until around 28psi. like i said before, green turbo(50 trim). it is also a great pump gas turbo. don't get me wrong though, a huge turbo, such as a 70 trim, is also good too. one of my guys is running one on his EVO w/ anti-lag. @ 20psi, his third gear and up feels like 2nd gear w/ an EVO III @27psi. but he redline is 8500RPMs. keep that in mind though b/c there's a lot of other things to consider here.

I originally wanted to go with the 57 trim, and the more i think about it, the more it makes sense for me to use that turbo. ill be able to get 500 whp from it with some work, and 400 whp will be somewhat easy.... btw ive desided to go with the catless new dejon tool exhaust. so that means ill be buying that and either dsm link or a lightweight flywheel and act 2600 this month. which should i get dsmlink or the fidanza flywheel and act 2600? (off topic)

i think the 57 trim should be good enough, does everyone agree?

 

[BrokenTsi]

I'd rather trust the act flywheel to not explode and kill you. I gotta put a scattershield on my trans this year, im getting too fast to be safe says nhra regulations.

 

[tstkl]

are fidanzas known to explode?

 

[BrokenTsi]

They probably dont, but in my personal opinion, I like to stay away from the idea of running a super light flywheel, ive been using the stock one for years, but if I had to upgrade, I would use the act flywheel. Its lighter, but not dangerously lighter. I'm sure it will be fine, but thats the one thing im kinda sketchy on when it comes to performance/aftermarket parts.

Here's a bunch of nice pics that show what happens when a flywheel shatters. http://www.diamondstarmotorsport.com/threespeed.shtml

 

[tstkl]

saw a vid of that same car (i think) going down the track when it happened... i think ill take my chances, since an aluminum flywheel is stronger than the stock ones anyways...

 

[Turbocharged]

I second the ACT flywheel. I dont know of any other flywheel that is SFI certified for racing. The fidanza's are cheap IMO. They look like something out of a tuner magazine.

If you end up running a turbo that will build power past 7000 rpms, I would definately get a stronger than stock flywheel for the extra insurance.

 

[BrokenTsi]

I believe that you HAVE to have an SFI approved flywheel if you're going to drag race. I believe anything faster than a 12.99 you have to have a scattershield and an SFI approved flywheel.

 

[tstkl]

whats the act weigh in at? either way lets get back to my 50-57 trim decision...

 

[v2ner]

i'd rather get DSMlink than a clutch upgrade. a heavy pressure clutch will likely kill the fork...depending on how much you launch and slam gears. i don't know how much the ACT weighs in at but i'm runnin a quartermaster twin disc w/ a custom flywheel. clutch and flywheel together weigh in at just over 15lbs. no tranny and driveline problems for over 80 launches and still running strong. DSMlink, man.

 

[tstkl]

i actually wanted that before the exhaust, but that changed for i dont know what reason.... think im going to go with the 57 trim, anyone want to spit out some times people have run with this turbo so i know what im looking at? also, I STILL CANT FIND AN o2 HOUSING... i want one that has a mount for an external wastegate, but I want that recirculated. or I want one I can use with the new sbr cast manifold with the external wastegate on that and be recirculated
