500+ hp turbo...

[king_of_HTX]

I am looking for suggestions on a good turbo that will make at least 550 but still hit full boost kind of early. So far I am considering the Precision 6152E Dual ball bearing turbo from slowboy. I talked to a guy that had one and he said it is a pump gas monster and would hit full boost around 42-4600 with my setup. Anyone have any suggestions for anything that is capable of making the power but able to hit full boost a little sooner?


Oh yea... I have a brand spanking new td06h20g for sale in classifieds if anyone is interested.

Holset, holset, holset!!! Did I mention Holset? I would probably go with a Holset HX-40 or a HX35. Depends on your relationship (how you run it) with your turbo.

Why do you mean one of these?

So the HX40 spools up and hits full boost quicker than the FP3065? wow. i didn't know that.

Timing also has a lot to do with how fast the turbo spools. More timing, less boost = Quicker spool and good power everywhere.

In order to hit 500AWHP your going to have to be running Cams + a SMIM, Both of which slow your spool.

Looking at logs from my friends cars, Both running FP3065's, 1 running a ported 2G head, 272's, Magnus SMIM The other running a ported 1G head, BC 280's and a JMFab SMIM. They Both don't hit full boost (32ish psi) Until after 5K.

Fp3065 is really wonderful turbo .

HX40 is a big turbo. Even though they say it'sa bolt-on it's technically not. It isn't a tacky little bolt-on turbo where it will you hp straight up. You got to have a highly modified cars in order to get the power it is capable of.

I went for a 60-1 to a HX40. It will smoke it the bejesus out of it. People don't realize what Holset can do. Everybody just smucker at me and call me a retard for slapping on a humongous turbo made diesel 7-8L engine, but is it the fastest spool 360 turbo out there and when it starter spool it unleashed power and I can wave at the people left in the dust.

It really depends on which turbo you pick. A dual ball bearing does need 280/280. I mean you're contradicting yourself by putting in a low spool turbo and 280/280 cams that give at high rpms. I mean I see people out there with t28 and 16g out there with smim and 280/280 which takes away what their turbos are made for and give them what they aren't made for.

That what I'm talking. As you can see it is a humongous turbo relative to the engine block and will spank the other turbos .

hmmm... Holset you say?

I disagree with you there man. Again looking at his mods boost will be their realistically by about 4000-4500 easily again even stock motors have made boost with that turbo at that level plus it's dual ball bearing so if he's at 5000 rpms to make 500hp with that turbo something aint right. Again on a heavily modified motor you can run less boost to get to the same power because the motor is more effiecient. My turbo on stock motors see boost at about the 35-3600 rpm mark and again im having full boost consistently at about 3100 rpms because of the cams and motor being built plus i have .20 overbore. Here is a copy and paste of his engine internals from his profile Completely rebuilt w/ TopLine rebuild kit // Wiseco 9.0:1 Pistons // Eagle Rods // Ported Head W/ 3 angle valve job // Stainless valves // Dual valve springs & titanium retainers // Balance Shaft Removal Kit // Revised Lifters // SS Manifold studs // Prothane Motor Mount Kit // Kevlar timing belt // New EVERYTHING

please note he has a ported head and the fact that he is running higher compression with this motor he will easily see full boost to make 500whp way before 5000rpms

I forgot to put in my profile that I also have .20 overbore.

My point exactly and you don't need a inake mani to hit 500 hp nor do you need to be boosting at 32psi especially if, as in your case, you have a 9:1 or what your compression ratio is and an overbore plus a fully built motor and cams. Again i don't want to go on beating but you should see boost in the 4-4500 rpm range with a good tune and what you have. I have the smaller turbo and it's coming on just where i want it too and calculated that it would.
