i basically have every supporting mod for the T04R i had just picked up, i am getting a power FC, 1600cc secondaries, and a few other little things to run it....

i have a 2row greddy intercooler, etc etc etc, but the only thing not done to my car is having the engine cracked open and ported/modded....

it has an S4 keg with S5 externals....

basically my question is, what kinda power am i looking at with an HKS T04R, the A/R i believe is .96, what boost level will i be "safe" at and still decently "reliable"...?

i was thinking 10psi, 8psi?, i dont know....

thanx in advance, i may sound like a dumbass in this thread but it's far past bed time....

 

haha.. i like how you layed the 7up can down next to it to show comparison.. haha.. anyways.. with the power fc and some 1600cc injectors you can turn the boost up to 10psi easily and have it running dependably with some good tuning. that turbo should give it some nice power up top.. you probably wouldnt be lookin at full boost tll about id say 4200 rpms.. maybe just a bit sooner.. my stock ported motor was spooling up a 1.15ar at just about 5k. but the power was really good up top.. only thing id be concerned about is that manifold.. ssautochrome manifolds warp really easy.. ive had 3 different ones warp on me in less then a couple months. with it warped.. youll have lots of exhaust leaks and the turbo wont be working to its full potential.. just my $.02 anyone feel free to correct me..

 

with a polished compressor housing how can you tell if thats a garrett or a hks?

 

the bigger the difference between your primary and secondary injectors, the harder it will be to tune...

 

Only with the PFC.. Most of the other standalones can handle that jump quite effectively.

 

heh, first reply and someone is ripping on SSAC parts, i expected that though.

i am running one and i also installed one for a local, both on 300RWHP cars and both mainly daily driven and neither has had any issues with the manifolds. i suspect you probably had one of their older versions.

 

i had one on my rx-7 about a year ago.. i bought it brand new from them.. it warped within 2 months of me having it on my car.. i bought a vert recently with it on there.. it had a huge exhaust leak from the flange to turbo.. so i bought a gasket and ripped off the turbo thinkin thats what it was.. the flange on the manifold was warped so bad it wasnt even funny.

also my friend had a manifold on his.. warped in a few months.. i personally wouldnt use anything on my car from ssautochrome.. ive heard the wastegates after some work are good.. but thats it..

 

I think the turbo is capable of 500?

As a rule, keep it under 15psi for pump gas.
I think it'll do around 300 at 12psi to 14psi or so.

Sounds like fun!

probably 450 with race gas and a good tune, not sure if you'd be able to squeeze 500 out of it.

reliable is a tricky question, the lower the boost the more reliable it will be because power causes problems. 15PSI is a safe number for pump gas but 10 would be a more modest number and that turbo would still be a handful to handle even at 10PSI, more than enough fun for the street. or you could get a EBC with a scramble setting or a 2 stage MBC for a street and race settings, just keep it on low boost while cruising around town and flip it on when you need that extra shot of power.

 

common now you don't think a to4r is capable of 500? Isn't the to4r compressor wheel the size of a t66? I know (here comes his name again, lol) jrats putting down 491 on his t61 so I'm pretty sure at least 9 more hp is obtainable on a to4r, of course this is not taking into acount engine porting.

 

**thread hyjack**hey i have a to4 with a 60-1 wheel. is it the same as this guys turbo?

 

ahh.. +1 on that.. a EBC with a scramble setting will do very good.. im pretty sure ud like the way it feels at 10psi..

 

No, yours is much smaller than a to4R. Much better choice for the street however.

 

Love my TO4R, its a 67mm wheel and I'm sure it will support 500rwhp, if not a little more...but thats a much higher boost, 24-25psi...

If you want to see what it does on just 10-12psi, go the the kills section and watch my last 2 vids...it does just fine

 

One of Speedmachine's customer cars does 486 Rwhp @ 15 psi with a TO4R. I'm sure it has decent porting though but looks like this turbo should be able to do 500 with a little more boost.

 

it's not an SSAUTOCHROME, it's a Megan Racing....

better build quality and thicker flanges, doesent look like it will give me trouble!...

This is my turbo, i have the .96 AR and it's good for about 700rwhp....

so weither my car is ported or not, i can run near 15psi without worry?...

i have an S4 keg and S5 externals so i have a little bit lower compression....

 

Mind you that the "650ps to 700ps" output numbers are quoted for a piston engine and probably BHP at the flywheel.
The turbo will not do 700hp at the wheels on a rotary.

With that said, it should do 500 at the wheels on a 13B...

since nobody replied to what i asked, whats safe to run this turbo on a stock block?...

wouldnt 15psi be pushing it since it flows alot more air then the stock turbo?...

at 10psi and 12psi, what kinda power am i looking to make at the wheels?...
