It is nice to see these turbo kits slowly hitting the streets.

To be honest I was hoping for the 135 to pull a bit harder on the M5 then what was shown. A little disappointing, but none the less it pulls.

Lets see the race again on meth or race gas No one said racing had to be fair.

my friends modded 335 with procede, downpipes, i/c, dual cones, and exhaust puls harder on a m5 then that.....

he paid less then 2k for all of those used....something like 1700 bux...

This upgraded turbo 135 will have serious trouble against an m6 since its faster then the m5's.....

In my guys, the ratio of money spent is not worth it...

True.. However, I doubt its a cylinder head deficiency and more of a turbo deficiency.

The N54 already does pretty well on highways, but the power band in many cases begins to flatten out due to the turbo's running out of breath.

I would imagine these ASR turbo's will do the same, just not as drastic.

Again as I have stated before I think the limit of upgraded turbos will be the turbine wheel on these turbos, the power graph will plateau which means that it will hit its peak power and hold that power to readline it wont gain much more it will just be flat. Where upgraded turbos will probably make 45-70 whp more at redline that stock turbos but they won't continue to gain power because upgraded turbos will be limited on the turbine wheel selection.

I'm sorry but you're mistaken, these are not upgraded compressor wheels on stock CHRA's. It's a completely new GT cartridge fit into machined stock housings. We've posted several pics before in the past showing the difference between our turbos compared to stock. Putting larger compressor wheels on these stock turbos is a big NO NO. The stock compressor wheel is already too big for the stock turbine, which causes a great deal of cylinder pressure at higher boost levels. By increasing the compressor volume VIA a larger compressor and stock turbine wheel with these turbos, you're only making matters worse and decreases turbine efficiency especially if its clipped. Not to mention the fact the CHRA shaft on the stock turbos will never be able to support a larger compressor for prolonged periods without failure.

what turBos who done the work? what HP?

[sleepdoc]

That looked like a really strong pull to me. You can really see the power.

I'd love to see some videos of bolt-on 335's beating M5's up to ~160mph, unfortunately i never have..

the M5 must have been driven by a 300 lb driver with a 300 lb passenger and forgot to turn their M button on....

i've raced an m5... drivers equal weights... my car very similar to what you describe, but with intercooler, and LSD ... (he had exhaust but i think that's it)... from 50-120 or so... well.. i could get the jump if he left his power button off.. and hold sorta even.. if he turned all 500 horses on ... i was SOL

I want a set of those turbos just for the piece of mind I could put out over 400 WHP consistently with out worrying about the turbo. any body that thinks the stock turbos with a tune even compare are just fooling them selves. having a ball bearing turbo that will hold boost to redline is worth the money to me even if it didn't put out any higher peek hp numbers.

I agree and I'm impressed how the car pulled in the video

I agree with you totally.

[GreenPlease]

Nice kill

The SMG gives the M5 a pretty big advantage in this sort of race. Extra cog, faster shifting.

Why not just wait and get a turbo upgrade thats more than just a bearing upgrade, the biggest things that will help these cars make power is not just the compressor side of the turbo its the TURBINE side is where power will be made, if you increase the compressor side with the same turbine wheel your power band is gonna plateau. It will hit peak power then just plateau to redline, i would rather wait for a turbo upgrade that has a properly balanced turbine wheel and compressor wheel. I really would like to see what FP's turbos are going to be like and how they are priced compared to these turbos of ASR. I agree that it is nice to have that power carried to redline but I think research and more time will end up with a good set of bolt on turbos! Ill tell you what if someone makes a turbo that will bolt right on making 440-450 whp on pump gas with a GOOD power band and good looking power curve, for about 3500-4k I bet you could get a group buy of about 25-30 ppl easy.

No it didn't

Seeing that you can pick a used E60 M5 in the $40k range. I would rather pick one up and mod that. There are some beastly modded M5's out there. This was a stock M5.
