The best Pump Gas "Turbo" set up? [Merged 5-7]

[kpt4321]

Everyone needs to stop calling that "bolt-on" PTE turbo a T3/T4. It is NOT a T3/T4. It is simply a Garrett CHRA with a cast turbine housing that bolts up to our stock manifold. I don't know if anyone has ever been able to identify/verify the fact there are 2 diff. A/R's available in the bolt on housing.

It has a T4 compressor wheel, and a T3 turbine wheel. For that reason, it's somewhat logical to call it a T3/T4.

You are correct, there is only a 0.63 A/R turbine housing avaliable. I have no clue why they try to say otherwise.

No, it only has the .48 or so turbine housing available.

Thank you for the clarification Ben, I knew it was one of the two.

Since when is a E50 (50 trim) wheel a T4 wheel? SCM-61? That's a GT40 wheel. T4 wheels start out with the T-61 and go up from there. Far as I know, none of the bolt on PTE turbos use any true T4 compressor wheels.

I believe that NOSLO2PT0 is correct about the PTE turbos.

Now I have a 91 AWD getting built right now. I have a built 2.0 shortblock with 8.5 ross pistons and crower rods from slowboy that is said to hold 700 whp, and I have a built tranny coming back from shep. I also have a AEM stand alone and all of the components to make an extremly fast car with exception to really big injectors (I have 550s now) and a turbo. Now from what I have read the 50 trim t3/t4s are what a lot of people are using. I was wondering people's results with the GT32R and the GT30, and the same from PTE. Does anybody have dyno results or opinions on what may be a better pump gas street turbo.

 

[Black94TSI]

IMHO the bigger the turbo the more power you will make on pump gas. Just basing off my experiences with hondas with a T3/TO4E 57 trim you could make 400 WHP on pump gas with a well prepped motor and a great tune, but it would take 18-19-20 psi to get there. Run a T3/T67 on the motor and people are making 430 WHP at 13 psi, so then if you cranked the boost up to 18 or 19 PSI you would blow the 57 trim out of the water. Just my 2 cents, i'm ready to take any flak as long as it is nice flak and backed with real world experience, not just what the compressor map "tells" you

 

[1fast97gsx]

I'd say a 50 trim is right for you .. I'm running a 56 trim and on pump gas a properly supported 50 trim will blow it out of the water I think. Once race gas and more boost comes into play its a different story. I'm running 8.5:1 ross pistons and eagle rods in my car ..

 

[93formula]

I will agree with your saying that bigger will make more power, but with a pump gas somewhat street driven car bigger is not always better. For instance, I could have a huge turbo that has a really peaky powerband that would make say 450 whp, and still have a very flat powered 430 whp car beat me because of the powerband. The dyno numbers are nice, but I would rather have something that performs better. The area under the curve is more important to me. By the pump gas statement, I'm saying keep it in a safe level of boost for the street, I'm guessing 22-24psi (I could be wrong on this estimate I'm just getting into DSMs) So I'm looking for a efficient turbo around the range of 18-24psi.

 

[1fast97gsx]

yep 50 trim it is ..

 

[guitarXgeek]

I'm in your exact position, looking for a good streetable turbo to run on pump gas. So far, the 50 trim with a .63 a/r seems like the best one while maintaining a pretty decent spoolup (little under 4k).

Or a 60-1 variant wheel. I bougth a 50trim and wish I had a bigger turbo. The 50trim is like the 16G a few years ago, we all thought it was the bomb until we learned that going larger with better technology makes us go faster. Hense the newer style wheels that are much larger than 48lbs/min like the 50trim.

I'm gonna run a PTE SC61 next year or something along those lines. Will be running a 6 bolt with Weisco/Eagle on my car. You have lots of motor, don't get a small turbo like a 50trim you won't be happy with it.

 

[93formula]

See that is what I'm scared of, buying a smaller turbo and not being happy with it. I would like something with good spool but I also want mid 11's at 5800 ft altitude. I'm not sure if a 50 trim will do that, correct me if I'm wrong.

 

[kooka]

please dont put a 50 trim on a fully built motor.

 

[allturbo]

For the sake of comparison the most power I've seen on a 50trim/pump gas is dre's car. Add on to the list if you know of any other pump gas whores

1) Dre / 503awhp / 50 trim/ 2.0L / http://www.twingles.com/ideck/
2)
3)

BTW, depending on wether 93formula's car is going to be a c16 sipping street/strip car, or a pure pump gas biatch, I'd don't see anything wrong w/ puting a 50trim on a built motor if he is going for the latter.

I agree with you to an extent ... however I have a built motor ( ross / eagle with 1g head ) and I'm running an SC61 and I don't like it. For the street it's just not fun. It's a drag race only turbo. There's too much lag to mess around with people on the road without hitting insane speeds to catch them ( modded LS1s or other sub 13 sec cars ). It's more of a drag turbo but if you want something fun on the street and capable of 11s I'm a 50 trim fan. 3052 is also becoming a good choice imo.

Yup, especially at your altitude. One guy around here runs this turbo on 91 octane and it's unreal. He ran high 11's on 91 pump at 4800 ft. Oh ya did I mention he had a stroker. Regardless, this is a incredible turbo that won't dissappoint you.

How much boost? With that turbo and a stroker at decent boost levels high 11s would be a dissapointment.

You have to remember that he was using 91 octane and he was at 4800 ft. above sea level. Those are pretty impressive numbers for those kinds of drawbacks, IMO

 

[93formula]

Has anyone tried the GT garrett turbos like the GT30R and the GT32

 

[zross1]

I think he was at around 20 psi, but I could be wrong, but like stated above he was on 91 octane at a elevation of 4800. Now throw in the race gas, turn up the boost to 30psi and you're looking at close to 10's.

FP3052 is gt30 based turbo, and it is awesome to say the least.

 

[sunflashx]

24 psi on a FP3065. It's also low 12's, not high 11's. However its roughly 13 mph faster than the old 2.0L/50 trim setup, I'm hardly dissappointed. The ET has lots of room to improve.

Welcome to 4400' NHRA elevation and 7000-11000 actual corrected value.

http://www.rmrracing.com/2004/drag/drag-strip.htm

The fastest GT40 powered car is going 124 mph, with two runners up coming in at 122 mph and the only AWD car to break 130 mph had a T66. Feel free to come to our track and share in the dissappointed at any time.

 

[IMMORTALSPYDER]

Nobody's recommended the FP Green yet? I'd say go with that or a 60-1.
