This thought might be somewhat of a pipe dream, but I'm wanting to do some planning for if/when I max out this 60-1 I just put on the grm car. Everything I have read says the 60-1 runs out of steam in the 500-550whp range. It will be great for the grm challenge and the few IFO's I will get to this year. I'm thinking I may want to break into the 9's one day. I can recommend turbos all day for stock block cars and fast street cars, but I'm lost when looking past this turbo.
I'm thinking at that point, a T4 twin scroll turbine housing is probably the way to go, but have no clue what size. Kinda taking a guess of a .88 a/r twin scroll t4.
-
HX52 FTW :noel:
-
I never seen a sohc put down good numbers with a 60-1......
-
I was originally thinking holset, but with any oem turbo, there will be some sort of compromise. If I get into a financial situation to buy a perfect turbo for my car, I will.
-
6262.... its what the ballers where running last week.... probably moved on to a bw or gtx something by now, should be able to jew... :Jew:
-
Damn, the 6262 is cheaper than I expected. I thought I checked once and it was $1300.
I need to check into vbands. I have only bought them as a kit, never used one directly on a turbo, don't know where to get the other flange and clamp
-
Mike at LSD quoted me lower. might give him a try if your serious. im not sure what im getting yet. was getting a 35r... may be a 6262... maybe smaller turbo like a 30r/5855? or someshit.... anyway he can hook it up on PTE shit.
-
V bands on ebay. 3" with both flanges and clamp cost like $25

Go here: http://www.aptuning.net/Garrett_GT_Journal_Bearing_s/50.htm (http://www.aptuning.net/Garrett_GT_Journal_Bearing_s/50.htm)
Or try a CDM GT35. Due to the cost, a Holset will probably be your best option.
-
500-550 will get you into the 9's. Work on your suspension and driving, faggot.
-
My suspension is solid for the current power level. Next time I get to the track ill crank it to nog and see if its still good. I know suspension setup is almost more important than the hp to get the time. My launch could use some work, but my driving is solid once the car is moving. I'm thinking a bit into the future right now, I can't get a $20xx challenge car into the 9's without a lot of budget objections. So, I plan to start aiming for 9's after this years challenge. I do really hope to see 10's next time out though.
-
so whats your best time at the track?
Invest in a go pro, and slap that bitch to the side of your car and point it at your wheels and do some suspension tuning with.
-
Best time is 12.5/ 1.7 60' at 14psi on a worn out eBay t3/to4e. Broke my traction bar so I couldn't raise the boost any.
Got a JK traction bar now and put the 60-1 on. I'd like to touch 10's the way it sits right now.
Z6/vitara/eagles
Sewell ported head/delta 272-2
Home made top mount
3" hood exit exhaust
3" charge pipes
850cc injectors
23 M&H slicks
I picked up a go pro since my last trip to the track.
-
Work on suspension and launch.
-
I ran a 6262 two seasons ago, until a few chunks of Vitara went through it. :( It was a great turbo that I didnt get to push its limits on. Cheap ass intercooler.
Building around an S366 with a .91 T4 twin this year. We should see how it works out come spring.

Dieing to see this ting since you told me about it. Twin scroll setup?
-
fuck precision turbos.
-
Comp turbos are pretty cheap/good results.
-
fuck precision turbos.
Yes.
-
Cheap twin scroll
-
I'm pretty set on twin scroll when the time comes. I'm going to push this 60-1 as far as it will go, then see where I am in life and what goals I have in mind.
Aren't there some major changes needed to the car safety wise once you hit 9.99?
-
Check NHRA rule book :noel:
-
9.99 or 135 you need 10 point cage (cert'd), window net, neck brace, etc. Most FWD will see 135 in the high to mid 10 range. Once you see 9s, you'll need a suit, gloves, boots, and licensing. Most FWDs will see 150 by the time they see 9s. At that point you'll also need a parachute.
I already had a 10 point myself. But I'll still be looking at 200+ for cert, 250? for license, plus physical (copay?), parachute, fire suit, etc. Probably another 2k just in added safety shit.
-
That's what I thought. I may not be in a hurry to hit 9's. lol
-
bah, first ones free, maybe more if they dont remember you :Jew:
i remember Ross out at the track with no safety other than a helmet running a couple 10.5s then he trapped a 135mph and they where like WTF? get out of here! lol
-
I know I can hit 9's once, but then what. Part out the car?i guess I could slowly add the safety stuff, but its crazy expensive to do at once.
-
Run 11s before you worry about cages and shit.
-
I have no doubt my next trip to the track will be fast enough for a roll bar. With the small amount of power I was putting down last time, gaining a second wont be hard at all. Also working on some aero stuff.
-
give me a part number for a bw, garrrett, turbonetics or greddy and i will see what i can do
-
HX52 is where it's at. Got a "rebuildable core" off ebay for $150 and it had so little shaft play it was practically non-existent. Awesome turbo. Guys have made over 700 easy. Some over 800.
-
I don't have a turbo in mind to give a part number. That was the point of this thread. Trying to decide which one to go with if/when the days comes.

I really, really, really want to see someone torture test a batch of those from random vendors to see if they're worth what they want for them.
For ballers?

Triple ceramic ball bearing fuck oil lines for life. Simply plumb water and you're ready to rock.

But will it blend... I mean spool?

500-550 will get you into the 9's. Work on your suspension and driving, faggot.
A busted DRAGIII t3/t04e kit on a B20 with cams, shitty street tires and peeling out through 4th still netted me a 12.3 @ 128....about 8 years ago. Work on your driving....1.9 60ft (I can't drive either)
Or add a shot of gas.
I'm running a 60-1 on my setup(now) as well, personally I have a cage but none of the other safety shit... Next time(if ever) I take it to the track my goal is to get booted out. :D
-
1.7 60' on a 12.5 run sounds like solid driving to me. Lol. 14psi on a worn out CDM turbo did work. Going to IFO in 2 weeks with the 60-1 and as much boost as I can get on 93 octane. I'm hoping for low 11's. I have all of the safety shit for 10.00 and 149mph. I'll switch to c16 and a bigger intercooler after this years grm challenge and head for single digits.
I think I have decided to hit 9's on this 60-1. If I can't do it on just boost, I'll add a 50 shot or so. After that the car will get an N/A J35 and see where that takes me. I don't want to spend the loot it takes to run 9's more than once.

Seems legit, I knew a fella that was his only goal for building a car, run a 9. Some stupid tubbed out new bettle chassis with a big block. Immediately after the first 9.9 he ran, he sold the car.... I think it's somewhere running meth and 8's now.
-
NOthing wrong with precision... Hit speedfactory up and ask for MAtt. Getpowerhouse has deals on them too... 6768H BB CEA... Yum
-
NOthing wrong with precision...
Except for their flimsy billet wheels. You can't hog out the root like that and not expect to have issues.

THey work fine. I prefer Garretts myself, but have NO issues with Precisions... Unless your spinning shaft speed through the roof consistently... You SHOULDnt have any issues, not that they havent in the past. Im aware of the issues, more often than not though, its always teh JB ones
-
THey work fine.
and last as long as a chinabay pos
-
HAve you run one? Me thinks no.
-
Personally no, enough people around me have lol.
-
Precision certainly had some major issues when Garrett first cut them off. Their current generation of turbo's I would have no issues running.
They are one of the current favorite turbo's of the 2.6" inducer sled pulling class, I don't know that there is a more abusive form of motorsport to a turbo then a class limited by turbo inducer size. Where they push these things to 80psi+ on a single turbo, with almost inconceivable shaft speeds. Obviously there are failures, but no more then any other brand.
-
Shit, those things must be knocking on 200k rpm
-
THey work fine.

If the billet wheel ones survive a dyno tune without coming apart, locking up, or leaking a bunch of oil then they seem to last a long time. I'd guess they run a 10% failure rate out of the box.
