Not really....but, have fun blowing up your motor...

 

They didn't pull on M5's, it was about even but after 130 the M5 would creep away. It should beat a stock 996TT.

On the oil in the intake, FMIC pipes, etc., very normal on a modern FI motor.

On a FI motor, whenever the PCV system is routed back into your intake, some oil will get in there, in your intercooler as well, a catch can is a great way to elimate this, as oil will reduce the octane level as well.

 

How do think I'll do that driving it? You're real bright..

 

Thanks drew, At least you know wth your talking about from experience.

 

You guys may rag on Jmoney all you want, but he has yet to offer less than sufficient proof of his statements, nor does he do so in a degrading manner to the rest of you.

A few points:

In FI cars, the oil in the charge pipes is true. The catch can is a nice mod to take care of that, but you guys make it sound like he's dumping quarts of oil into his engine... we're talking drops and splatter, hardly anything that would cause engine failure.

I'm willing to believe 93 octane if ONLY because of the direct injection. I think this is key to the package, and it really sets new boundaries on what's possible with stock set ups. This is therefore NOT like the supra. It's better.

All the 335i's have intercoolers. Anyone who says otherwise is false. End of discussion.

The drag radials really helped here, especially with a car that makes so much torque below 4k RPMs. That is a respectable 60ft time, but I think it could be even lower with the numbers we're talking about and drag radials, but that's just me.

Anywho, good luck with your projects, I look forward to seeing what this can do.

 

This is very true. I've done a lot of work on DI systems and the whole point is to create more power by burning the fuel more efficiently. This also does a tremendous amount to prevent knocking.


As another poster replied, I think he was referring to the "oil" coolers not the "inter"coolers. BMW has switched suppliers of them (not sure if it is a design change or if was a manufacturing defect) and are including them on all 335 models now. These units were on back order for 30-60 days and gave many 335 owners a chance to try other BMW models while they waited.

 

It really doesn't sound like its a few drops if its decreasing performance...it sounds like there is increased pressure in the crankcase and oil is getting blown past the rings. Oh well, should be interesting how long you can push that much power on that motor...

 

i was refering to his question of, 'does the 335 have heat problems'...and was referring to the oil cooler heat problems (these are the few people who had their car bought back by bmw), not about the intercooler...i know it is intercooled

 

On a boosted motor, blowby would happen in the other direction i.e. from the combustion chamber to the crankcase. The pressure would then accumulate within the entire crankcase, and then head out the breather at the top of the engine, taking some oil with it in the process. If that's the case then maybe the rings are to blame but I would not be so sure. It would take a LOT of oil to have an impact on performance, though. It sounds like something else is wrong, unless the oil is messing with a sensor.

 

On another note, I have no problem believing 93 octane at 14psi on this particular engine. Though I probably wouldn't push it much more than that.

 

I'm actually really interested in seeing what kind of numbers this thing is capable of on 93 octane. It would depend where the turbos are in their efficiency range at this level, but I would bet there's more to be had with some more boost and a larger intercooler.

 

They are very capable of those boost levels on 93 octane, not trying to debunk that, but he made 423 WHP, lol, I don't see that happening without race fuel and added timing to make those #'s and run that trap, but I could be wrong, if so good stuff.

 

He also made 490 wtq... which is a HUGE contributor to this. With a good 60ft time on drag radials and that kind of torque helping in the second half of the track, I'll believe an 11.9 on 93 octane.

A lot of people on here are skeptical, and they have every right to be, I just think the package is capable of more than everyone else thought.

 

Not sure if 490WTQ is doable at 14psi, unless it was a quick spike.

Oh those cars are the real deal, with turbo upgrades it's going to get VERY interesting.

 

I can't wait til some one just says F**K it and go ***** out with a motor until it pops.
