Turbo Saleen final steps

[Meikol02]

Nope...neither did mine (although the new motor does!)

Something for the next round of mods Jimmy!

 

[Saleen S281]

Did your saleen come with forged internals?

No, its only on the Saleen Extreme, the one I have its a stock 3valve with Saleen UDP, intake, catback, tune, suspension, interior, body kit, wheels.

That's the plan Mike!

I believe the delete plates and exhaust are the biggest thing and I can easily see a 50 hp increase just by doing these. Jojade on here picked up 40rwhp by deleting his CMPs. He has a powerhouse kit though.

Yeah I saw that, his car moves!

I know! 10.89 making 470 rwhp! Eat that 5.0's!

Now that I think about it, I think this is on a bone stock car with the stock injectors with 91oct fuel. I have a Magnaflow/Saleen exhaust, cmdp, 39#injectors, 93 oct, Saleen udp, and Lito tuning it, so I'm guessing I'm at least @ 430whp @6#s. I'll know more when I go to the track.

If you look at the chart you will see the gain from 6 to 8 psi is minimal and then there is a huge gain from 8 to 10. That is because we had it tuned for 12psi so the timing was sucky for only 8psi - PLUS YES 91 octane tune and this is a Mustang Dyno not a Dynojet number. We have tone of report from customers making 550 at 10psi on 91

 

[Granatelli]

So according to that chart, I won't even make 400whp at 8psi?

More thoughts - I looked up the numbers from a different car that made 461hp and 445 ft/lbs at 8psi at 23 degrees timing. The dyno figures from page 11 (that car never went over 17 degrees total at WOT

 

[Saleen S281]

Ok thanks, that makes more sense.

I keep coming to this thread looking for video....is it running?

Lol, yes its running, just no video yet. I'm finally off this weekend, so maybe I can get one.

 

[Saleen S281]

That was weird, I started the car to move it around my yard and it shot blue smoke on start up, then it clears up. I haven't driven it hard and hardly any at all, any ideas?

What turbo are you running and do you have an oil restrictor on it?

Turbonetics 76mm and no restrictor, I asked JR if I needed one and he said no. You're thinking turbo seal leaking?

 

[Makdaddy]

Q. Does my turbo require an oil restrictor?
A. Oil requirements depend on the turbo's bearing system type. Garrett has two types of bearing systems; traditional journal bearing; and ball bearing. The journal bearing system in a turbo functions very similarly to the rod or crank bearings in an engine. These bearings require enough oil pressure to keep the components separated by a hydrodynamic film. If the oil pressure is too low, the metal components will come in contact causing premature wear and ultimately failure. If the oil pressure is too high, leakage may occur from the turbocharger seals. With that as background, an oil restrictor is generally not needed for a journal-bearing turbocharger except for those applications with oil-pressure-induced seal leakage. Remember to address all other potential causes of leakage first (e.g., inadequate/improper oil drain out of the turbocharger, excessive crankcase pressure, turbocharger past its useful service life, etc.) and use a restrictor as a last resort. Garrett distributors can tell you the recommended range of acceptable oil pressures for your particular turbo. Restrictor size will always depend on how much oil pressure your engine is generating-there is no single restrictor size suited for all engines. Ball-bearing turbochargers can benefit from the addition of an oil restrictor, as most engines deliver more pressure than a ball bearing turbo requires. The benefit is seen in improved boost response due to less windage of oil in the bearing. In addition, lower oil flow further reduces the risk of oil leakage compared to journal-bearing turbochargers. Oil pressure entering a ball-bearing turbocharger needs to be between 40 psi and 45 psi at the maximum engine operating speed. For many common passenger vehicle engines, this generally translates into a restrictor with a minimum of 0.040" diameter orifice upstream of the oil inlet on the turbocharger center section. Again, it is imperative that the restrictor be sized according to the oil pressure characteristics of the engine to which the turbo is attached. Always verify that the appropriate oil pressure is reaching the turbo. The use of an oil restrictor can (but not always) help ensure that you have the proper oil flow/pressure entering the turbocharger, as well as extract the maximum performance.

Journal or BB. I am running a .065" restrictor on my precision 6765 Journal Bearing turbo. Oil past the seal is a possibility, but I would want more proof than just one startup. How many miles are on the turbo?

 

[Saleen S281]

Its supposed to be a ball bearing, JR said their kit comes standard with bb.

 

[retfr8flyr]

If it's a BB turbo you will need a restrictor on the 3v engine due to the high oil pressure it runs. If you don't have oil problems without one you will be the first.

Hmmm... Ok thanks. I'll get the numbers off the turbo and call Turbonetics and see if they can tell. Also, I noticed when I first got the turbo, the center section was black, since I've been running it, its started to look a bit amber/rusting, I checked the oil feel line and there were no kinks. I'll try to take a pic tonight. Thanks guys.

 

[retfr8flyr]

The center section is steel and it's probably just turning the paint from the heat, I would imagine it's painted not coated. You will need about .040 restictor if it's a BB and, like Fuel, about .065 for a journal bearing.

Doesn't that kit have a screwy oil drain setup? Did it require you to punch the pan and run a drain line into it? I was thinking it had a different kind of drain setup.
