I would say 550's won't take you very far. You'll need something bigger.

As far as streetability, it's all about what you can tolerate. Don't expect full boost till about 4000-4200 RPM's.

 

The 255lph fuel pump will only supply enough fuel for 450 flywheel hp. I would recommend a larger fuel pump, aftermarket FPR , atleast 720cc injectors and some type of electronic fuel management system to fully utilize a 60-1 compressor.

 

go with a smaller turbo.

 

yea i want to most horse power but still be a daily drive.
....
i just don't know if its right for me.

It's not the right turbo for you. It will be too slow to spool up.

A turbo this big works the best over 25 PSI, you will blow your engine up if you try it with pump gas. So, it's not "daily drive".

You can make the same power with smaller turbo on a daily driver (pump gas).

 

Im am sort of in the same ball park, except i have some more supporting mods. I already made a post in this section about "Help me spec out a turbo".

Sounds like the 60-1 is a tad too large. I was told that the 20g and FP green can help me get to my goals of 450-500 crank HP, and deel 11's in the 1/4 mile. But, i would like to know of a Garrett T3/T4 equivalent or maybe Kicked up a notch above the 20g...

thanks

i'm going with the 60 trim next month. i plan on it being a daily driver...but i really dont care about lag. garret also has the 57 trim compressor that may be an option for you.

 

A friend of mine and fellow DSMCA member just dynoed his 60-1 a few days ago on his 97 GST. The first run was on pump gas and was untuned Here's his first run (18psi I believe)

His best run was with some C16 in the tank and at 29 psi. That run netted him 467 HP (SAE corrected). Here's the 467 HP run And he was still getting some knock on that final run. I believe he's still using the stock intake manifold and that's why the torque curve dropped off after 6500. He does drive the car and on the street. His only problem is being fwd. He says he can spin the tires on the freeway if he hits going 100MPH. If he was AWD, that thing would be very, very fast on the street. Hope it helps some!

 

that sounds pretty promising.. Is his boost curve similar to his torque curve? Meaning, his spoolup time show the same curve if plotted against rpm?

It looks like he may not have gotten it spooled untill about 4300 rpm or so. Of course, that would be more helpful on his car...Mine is AWD...so i think this thing would be scary fast.

It looked like his mixture was pretty good. nice and safe at 12:1 right? except towards the top end of that 2nd run at high boost...looks like it started to lean out.

What kinda fuel mods did he have at the time?

I wonder if there is an intake that can breath a little better in the top end...aside from a Sheet metal short-ram intake...I dont wanna lose a bunch of low end torque.

Man, thats crazy HP... thats like 550 or so at the crank...

I was trying to compare all the turbos that i have available to me for my needs, and a couple different trims besides the 60-1. So far the 20g looks like its pretty efficient in the at the outer edge. the Peak airflow at 2.0 PR has a Efficiency of 68% it looks like. I couldnt find any #'s for effiicency rating on the 60-1 map, so i have no idea how far down the Efficiency drops at the outer limit. the V trim wheels go all the way down to 55%, and the H trim goes down to 60%, still not promising. The only 2 turbos im misssing info from are the FP Green...i have no idea how it will compare to the rest of these turbos, and the 60-1. It definitly looks like it flows the most air of all the ones i picked in this range. The FP Green, i have no idea how this compares to anything else tho. All i know is that it "Supports 550 HP", but how WELL does it support it, u know?

..Damn 29 psi, thats crazy. i Suppose i wont have to worry about ruining my engine w/ that much air as long as i have it tuned right...

Thanks guys
Chris

 

I believe he's running 720's and a Supra fuel pump. Not sure about anything else he has or other specifics. I know there are some guys in the club who are running Greens, I'll see if anyone has put up a Dyno sheet. The only way I could see getting more flow would be go with a sheet metal intake and maybe use a 50 shot to spool it up (unless you go all out and do a 2.4 liter swap to get it spooling). Turbonetics might be able to give you some effiency numbers. I know they have maps of a lot of the compressor wheels but I don't know if anything else is posted. Have you considered AGP Turbos? I know they have some high flowing turbos and they have their efficiencied on there. I'll try and find some Green dynos.....

 

Andre has a Green with 8cm housing and a lot of supporting mods. Here's a complete listing of many dyno runs with the Green.Green Dyno runs

 

Thanks buddy. Ill try emailing Turbonetics for those #'s. Im not sure i wanna do a 2.4 swap..ill lose my RPM's. Of course, it maybe worth it down the road if i have to get new pistons and stronger rods.

AGP, i think they have good deals dont they? I remember lookin at their website before.

Im worried about how much the intake charge will get heated up, cuz the last thing i need on a high strung motor is hot air.

Thanks
Chris

 

AGP does have some good deals. Some of their turbos are absolutely massive! If you're really looking for a quick spooler, they do have ball bearing tubos that I've heard good reviews about. I'm sure no matter which way you go, you'll have a rocket of a car. It's just a matter of picking the one that's tailored to your needs the most. As long as you can keep it tuned, it'll fly. Good luck with it!
