Running Mid 11's, Want 10.99... gt35r or 60-1

[BlackHawkAWD91]

Alright, once again I want more. I currently have a PTE 50trim internal. I have run 28PSI at the track trapping 122 mph 1/4 and 97's mph 1/8, I have run 30PSI but not at track. At most I think 1 more MPH, maybe 1/10 faster.

I believe I need 127-130 traps to pull a 10.99 with my driving skill level. I still run a stock intake manifold, I know that hurts. However, that alone will not be enough for me to reach 10s. My question is this. I have heard over and over a bolt on gt35r is very limited due to the .63 ar. housing. Most get around 500wheel and they are done. That could be enough for 10s, but 60-1 with stage 5 wheel produce 500wheel HP also and cost much less. I also plan to use a external off the 02 housing with the new turbo hoping this will add performance.

Will a 60-1 be enough? Would I be better off spending extra $500+ switching to a t3/t4 and running a .82 ar 60-1 or a .82 35r (in that case add another 750 or so extra cash)

Another turbo is the SCM61, however looking at dsmtimes.com that turbo isn’t very impressive, most trapping what I am now.
I want most bang for dollar to get me into that 10.99 all boost.

Thanks for the DSM brains that reply.
Happy Boosting!

SCM61 = GT35R compressor wheel on a regular stage 5 turbine wheel. The .63 A/R GT35R has made ~630 WHP on a Honda, so if it's getting maxxed out at 500 WHP I think it might have more to do with the mitsu exhaust housing than the turbo itself. I personally would just run an SC61M.

The .63 A/R GT35R has also made 587whp on the srt-4's 2.4L with 30psi

I think a 60-1 should be more then enough to get you where you want to be.
edit: bad math

 

[Al_Scrap_Iron]

SCM61 + supporting mod = 140mph in my case, love this turbo...

i have gone 124 mph on a stage III .63 60-1. this was at 23 psi. stock intake with HKS 272s, FIC 650s, AFC and 2g maf, with the wastegate routed into exhaust.

the 60-1 has more than enough for what you need. i feel that at 30 psi, this turbo would be good for easy 128 mph, probably more. the top end pull is reduculous, even at 23 psi...going external with the wastegate would surely help even more.

for comparison's sake, i also have an FP Green sitting on my shelf that feels anemic compared to the 60-1. the difference in top end thrust is really eye opening....again, stock intake mani.

i attribute this mainly to the .63 housing (MUCH bigger than a mitsu 7cm). i actually think that the 50 trim compressor has more than enough of what it takes to get to 130 mph. the reason it rarely gets there is the compressor is constantly matched up with PTE's housing or a mistu 7cm.

a 50 trim in a .63 or .82 garret housing would make for a nice flowing turbo. i'd imagine when Dre made 503whp on the 50 trim it was with a large turbine and a large exh housing.....

Yes you are going to want to run a larger exhaust housing. Most Mitsu TH's are just to damn small. I would go to a Full T4 and not a T3/T4 turbo. You will loose your low spool but who cares.

 

[Reese92tsi]

You have a very good setup but that Mitsubishi turbine housing is hurting your top end performance. A full T4 conversion with an external wastegate (dumping to the atmosphere, NOT routed back in) would be a good idea and it would probably get you really close to 10s. You should be running a Cold air intake being that you have the MAF-T setup, a CAI has been proven to add 2-3 mph. Higher airflow is also achieved by changes is valve timing, 5 degrees retard on the exhaust cam seems to yield great results. Also, 50 trims have been up to 129+mph.

It really wouldn't be necessary if the 60-1 could be in a 8cm housing internally gated. Here's an example of my "red pill" 60 trim compressor wheel in a p-trim exhaust wheel as a direct bolt up. It is good to over 500whp

Even made sure the 8cm housing has a wider diameter down the chamber.

38mm wastegate and flapper.

The Shodan from where you got the turbo?

 

[Byrd]

sorry to hijack the thread but i second that ^ and you said it was a direct bolt-on? no mods needed to make this fit?

 

[Shearer]

It all comes down to the budget you have to make this happen. You may be able to get a 10 out of the car with a bolt on housing but it will be an uphill battle to do so. A 61mm, 60-1, or 35r are all capable of making the power to run 10's. But using a restrictive exhaust set-up is not going to help. Just by replacing the stock stuff with a T3 header and housingon any of the above turbos will yield good gains all on it own, exhaust backpressure will go down significantly and a very good of amount of power will be gained.

 

[92GSXBaltimore]

it a 38mm going to be enough for that thing?

 

[peregrine]

sure if he runs high boost all the time.

 

[Steve93Talon]

An "8cm" housing is a Mitsu part. That pic is a Bullseye housing. It's AR is similar to the Mitsu, but it uses a conical style scroll for more efficiency. Your 50 trim should be able to get you 125-128 traps easily, don't give up on what you've got.

 

[Slippi84]

You do realise that SBR made 600 hp with a gt35r which is plenty to run 10.99 with awd. They did it on a 2.3 sure but still this was bolt on .48 housing!!!!!! So don't be fooled by the small exhaust side it can still make plenty of power. There is a whoel thread about it on here don't take my word for it.

 

[Coup D E'Tat]

Good luck trying to get that Bullseye housing/internal gate past 21 PSI

 

[spoolinawd91]

Why wouldn't it be able to go over 21 psi?

 

[Coup D E'Tat]

Why wouldn't it be able to go over 21 psi?

My gate blew open at 21-ish PSI. It wouldn't hold any more.

 

[Slippi84]

Wrong your internal gate was already open and the reason you couldn't go any more was cause the 38mm opening or w/e you have wasn't diverting hot air from your turbine, and it should have went to more like 25psi not 21.

 

[TimG]

Mine too. 21psi or infinite boost.

Alright WTF

 

[Slippi84]

My bad dog shouldn't have been a dick about it I had just got off from work and was too short with you. You are right the internal wastegate is a restictive devis but not cause it doesn't stay closed but because it doesn't flow enough hot gasses away from the turbine. That's why usually most external wastegates are 38mm or bigger because they are used to divert the appropriate amount of gasses. If you had a situation where your internal was closed you would boost creep pretty bad but if it were open all the time you would take longer to spool cause you would be routing away useable exhaust pressure.

I think you're confused about what Coup was talking about.
