getting into the whole turbo thing so i got alot of questions lol.

what kinda hp numbers will a .60 trim garrett be able to do safely. on a 9:0.1 comp 2.0 gsr? using a lovefab top mount

i am wanting around 450 on pump maybe more on race



if it wont do it what would you recomend.

 

60 trim is capable of 500ish

 

Not on pump gas for a honda. 60trims are similar to 50/57 and the like. about close to 380whp on pump gas, about 440whp on race gas. Period. The stage 3 exhaust wheel doesn't like to push any more than about 440whp. Is this an 89mmx84mm combination or just a 1.9litre 84mm bore stock stroke combination?

 

84.5mm stock stroke.

looking for a turbo to make that 450 pump or maybe more the motor is sleeved but i will be doing some time attack also so i dont want to much lag. i am prob asking way to much lol no lag and 500+hp lololol

 

yes, you are. And most FWD time attack cars are under 500whp. they are about 380-400. what you're seeing in articles refers to brake hp (bhp), not to the wheels. Most of those at that power level are also AWD applications. Even the best Tsukuba and willow run FWD cars are about 300whp.

You will not get 500whp without hitting boost threshold (lag). You're asking too tall of an order here out of a 60 trim. When you get above 61mm inducer wheel turbos like GT3540S, SC61, GT3682R, BW S362, etc. only then will you even begin to have 500whp on pump gas. and yes, they will all not respond the same way as your 60 trim. You also dropped your static compression a bit low for time attack and circuit, since those vehicles look to responsive off-throttle response on the circuit. Power is the last thing they worry about.

 

sorry i ment to say on race gas, but i ran a 60 trim on an LS and made 450 on 22 psi boost so i know that the 60 trim is good for 500 range. that was on a .69 exhaust housing stage 3 wheel

 

Get the GT3540S from shodan. Amazing turbo.

 

You're at the limits of that turbocharger, and that is strictly DYNO DEPENDANT. Just because it can be done, doesn't mean its a good idea. You should see your Intake Air Temperatures next time you do that. You're to a point where you're almost just blowing hot air into the combustion chamber. This is where you want to upgrade in size so that you can increase more efficient CFM flow into the combustion chamber, and tune with lower IATs available.

 

well unfortunatly i bought the bottom already built. i sold my piston rod motor when i got this one. it had 10something pistons in it

i am not looking to be competitive in circuit racing just wanna go have some fun ya know. really just want that 450 on pump. not really wanting more than that ya know. maybe later i will switch to drag and go bigger.

right now the motor makes 443 on 24psi on c16

 

Again, you'll need to upgrade to a larger compressor/exhaust combination to do that on pump gas. I have one customer that used my GT3540S Journal bearing

 

agreed that its max on the turbo. air temps on a 80 degree day with an ebay fmic were only 92, not bad considering, and yes definatly not capable of that power on pumpgas i agreed with that

 

so i need to start looking for around a .70 A/R compressor. what would you guys recommend for the exhaust side??

 

not nessesarily unless your more concerned with the power output the the overall performace then yes a bigger turbo is nessesary .63 should work for turbine housing the .82 is better top end but going to be more laggy

 

And you don't necessarily need a larger T04S cover to do it either. The T04E is just as potent. If the .63A/R uses the right EXHAUST wheel (notice the emphasis on wheel, not just housing) Then you'll still get the top end you need in the right volute. The GT3540 can come in an "E" cover .60A/R as well. The photo was simply the customer's preference.

 

turbo chemistry is so confusing lol

 

That's why you ned to trust shodan. He explaned everything to me easy to understand manor. Just tell him your setup,your end goals and he can something together for you.

there is the setup made 440 at 24psi on c16

i have a love fab top mount that i am wanting to install when i change the turbo along with a bigger intercooler.

really want that 450 on pump and 500 on c16 at least. i have been told a sc61 would be a good choice but i really have no clue. i need to find something to read up on to try to learn more about turbo sizing

i really appreciate all the help you guys are offering as well. people on the local boards were all snobs about it

 

440@24psi with the 60trim seems low to me. I was running the 60trim until a few months ago and I was making 475@20psi on 112oct and 425@15psi pump gas(91oct). It could have easily made 500whp on my set up but like everyone is saying that is pushing the turbo. I stepped up to the SC61 to make even more and I think something like that is what you are looking for.

 

Dyno results vary. remember, on most dynos are a snapshot of ideal conditions with hp being mathmatically calculated. So going through specific number + or - a few hp to the wheels is rather a moot point (as you pointed out at the end of your statement champLSinteg).

those photos are of ScreaminVTEC's turbo he just purchased for his kit that is for over 380whp-450whp on pump gas. He had similar goals.

 

what did that turbo run him. i am thinking i might just put this bigger intercooler on my car and the top mount with this turbo and get a retune. i know my intercooler is to small that might be hurting it

 

Peak horsepower is for a drag strip. If you're going to on/off/on the throttle a lot, you won't want the big laggy turbo just for an additional 50-100hp. If its a big track with long sweeping turns and only 1-2 hairpins, you'd want the more peaky turbo.

The thing most people don't get is a small turbo will still make a lot of torque. Its just that torque will fall off much faster, so you wouldn't be impressed with peak HP numbers. However, on a small track, being able to hit 20psi with a small turbo twice as fast as the next guy will help out more than some extra peak power.

The other thing you might want to do is go with a big supercharger. The link below shows the Magnuson kit nearing completion - with a ~500whp blower case attached to a B18.

well i will only be doing a few track days a yr. its more for me to play around with than anything
