Ok, here are a couple of photos. XS T04S kit w/ 60-1 wheel and all the standard supporting equipment. Probably pretty standard fare for this group.

Close up of the turbo side.

Looks good man. Hope you like it and it treats you good. Mine sure does

Is it laggy? I would really like full 15 lbs of boost by 4k MAX. looking to make over 400whp, but more importantly gobs of torque.

 

I've got a T04S and I love it... full boost by around 3600 no problem. Also made 350 rw torque at around 6000 rpm at 15-16 PSI.

 

Boost begins at clutch release (2K rpm) and climbs right to 13.8 lbs by 4K rpm. That's the minimum setting I can hold with this wastegate spring and boost controller. I won't go to 15 lbs until I've tuned it for this minimum setting, and I can't do that on the street anymore - the car is too fast for street tuning (the CHP has helped convince me of this). Huge torque differential compared to the twins. This spools just as fast or faster than the twins, while developing more power at equivalent boost.

I'm going to the track to get new time and trap speeds next week.

The lag stories of singles (at least of this size) is all smoke and bs. The technology has improved so much, there is no difference between these and the twins, except that you can grap ahold of almost anything under the hood except the exhaust or engine block because the underhood temps are 50 deg C lower (yet another benefit). I'm never going back to stock twins.

so it sounds like u really like this turbo....im lookin for 400rwhp.....is this the turbo for me?

 

Yes, this is well documented on the single turbo forum. As much as 420 rwhp on pump gas has been acheived, much higher on race gas.

Of course, you need the other supporting equipment to make this happen.

what size inj are you using? 1300cc? fuel pump?

 

PFC w/datalogit, 1300cc secondaries, Walbro, streetport, dp, resonated mp, cat back exhaust with wastegate plumbed into the dp, M2 smic, pulleys, Twin Power, this list goes on and on and on and on.....

Beast

 

what's the turbine A/R? and the compressor . Sorry to be so nosy, but it's much cheaper than me going out, and testing every turbo on the market.

 

I'm uncertain of the total specs - I just bought the to4s strip kit w/60-1 wheel. Whatever comes standard with that kit - I can't find the exact specs.

I know I like it.

Beast

 

why didnt you just go to4r? it spools just as fast and makes more power. i think someone here was making 440 on 1 bar!!

 

I haven't seen any T04R graphs here that impressed me. If you've got one, please send the dyno with mods list.

Anyhow, the "standard" T04S has

0.70 a/r compressor housing
60-1 wheel
1.00 a/r tangential divided exhaust housing
P trim wheel

 

Thanks, 'gasm. This is nice to know.

i thought the standard t04s came with a .84 hotside......

 

i also have a question about singles in genral, does it make the life of the motor shorter? i would think that stressing the motor to make that much power is not good but its not at that high of a boost setting. but i do realize pushing 15psi on stock and a single is different. i thought that it would be better because your motor runs cooler and it would be better for your water seal which is a common problem. the other thing to worry about is the apex seals and that has to do with tuning. so is there any reason to belive that adding a single will kill the motor sooner?? also, it is a ported motor with 2 peice 2mm Rotary Aviation seals.

what do you think?

 

1.00 hotside. I made 435rwhp at 15lbs with this turbo with almost the exact setup you have, but I have a paceported motor. You even cut the IC piping they give you the same way I did to make it work.

 

Wow - 435 rwhp......that's awful good. Gives me something to look forward to, esp. since as you said your setup is very similar to mine. I have an agressive street port - they went a bit 'outside the lines' of the regular street port template they use. As soon as Autonomic (formerly Checkpoint) gets their new AWD dyno in, I'm looking forward to going after the upper numbers.

What I'm loving is the torque band. The car is actually more streetable now than with the twins in non-seq. mode.

rzograbian - I don't think there are any long term studies on the lives of singles vs. twins. There's been lots of discussion, but no difinitive studies. My stock motor went 67K, my second stock port twin went 40K, then my stock port hybrid twin went at only 4K (bad tuning, not the engine's fault). I can say that even though the motor is making more power, it is doing so with less effort. Now, once you get closer to 400 rwhp, the key is dowel pinning. The motor is made of plates, and the combustion is occuring on the 'outside edges' of the plates. There's more and more force being generated by these explosions, and as you approach 400 rwhp the plates actually 'shift around' relative to each other, which stresses the water and oil seals. With the motor pinning, that eliminates (or at least reduces) those side to side forces. That, coupled with the amazing reduction in engine bay temps, would seem to logically indicate the single motor at equivalent boost levels should last longer than a twin (assuming good oiling and equal maintenance).

Now, when I put that GT-C front end on and the giant 32-row oil coolers, that will help even more....the constant drain of money. Speed costs money - how fast do you want to go? Or the classic - There is no substitute for cubic dollars.

Autonomic eh? Well, my 7 happens to be there right now its the black one with the TO4S. I too cant wait for the power of the single. I was wondering who Chris was talking about.

 

Hey, Billy - hope you get your car back soon. Yours was the first T04S Chris installed in a 3rd gen, and you were the guinea pig on the restrictor pills they put in the oil feed (the stock feed from XS being too small is what caused your first one to fail). I got the benefit of your misfortune, since mine got the bigger pill and is running GREAT! I also saw the dent in your rotor - welcome to the club on that one. I can tell you you're going to love this setup.

Might be going to Wednesday drags this week, but this weather might interfere. We'll see what kind of times this beast puts down.

Beast

 

Yeah, I'm in NY so I'm not even going to bring the car over here until summer. What exhaust are you running? I kinda want to quiet the car down a little but I dont want it to cause lag? You and I will have pretty much the same setup minus the pfc as I've got the new wolf. Good luck wed. Watch that diff.

 

I'm using the dp that came with the turbo kit, Pettit's resonsated mp and racing cat-back. It's not that loud - the hybrid twins had a much louder and harsher note to them. The big turbo actually helps keep the noise down. My neighbors no longer complain about my starting the car and shaking the whole community.

I know that an upgraded diff and those molly axles that RP sells are in my future......

Beast

 

Is there something I need to know about the oil lines???
