It's a problem on a lot of them but not all. I would say it is a problem on all that are running more than a single 255 though. Andrew Kisner is the first person I heard about doing it.

The return isn't the problem. The siphon is in the tank. Let's say that you have a 2g awd with dual bosch pumps and a -10an return. You will still have the problem. Sure the return is big enough but the siphon isn't and has to be drilled out in order to flow enough fuel or it will build up pressure.

Yeah, I didn't have a problem running stock pressure, until i installed my inline pump. Andrew has done amazing things, and I've known him for years, but he wasn't the first, there have been a number of people doing it over on link forums for some time now, but it seems you have link as well...oh well, it's a good find, whoever came up with it!

dsm-onster, thats exactly right, even with an afpr, you can't control flow, because it is simply not getting rid of it fast enough. Even if you upgrade your return line, in a 2g awd anyway, you will still be restricted by the tiny hole in the siphon.

Ok. Just clarifying. So you all arn't saying that the 1g, 2g, or n/t FPR does not get overrun by a walbro 255. It still overruns a stock FPR. Just that if you upgrade to an AFPR on an AWD 2g you may still get uncontrollable pressure at low load, because of an issue not related to the AFPR at all.

Thank you sir. It's the kit we just made for an EVO. Same kit already made 472awhp at only 24psi on 93 octane pump.

You came in a little late with the answer to the original question

. Where's that kit on your website?

Correct.

I dont know about modding a fpr. I personally wouldnt do it. I got the regulator and its going on tomorrow. CHECK THIS OUT. I F'ded up. Its too long of a story to type the whole thing but I was under my car and saw the elbow that was welded on to the compressor cover was rubbing on the motor mount. I fixed it. So on the way home i was smashing through 3rd and usually let off before i shift to 4th. Normally in 4th gear at 4500ish as boost comes on the car will knock EVERY TIME. I just did 4 or 5 4th gear pulls till redline and absolutely nothing. Or at least from what i could see on my dash. I have the light come on at 3 counts with dsm link. So this whole time we've been tuning and working with the car I might have been getting knock from the compressor cover hitting the mount. DOH! Hopefully that is the case and we can tune for more power.

I Guess I don't know my BW turbos huh

It thought it looked like a knock-off because is so chunky. But hey, If it works it works. 472 @ 24 seems pretty good ...I can't argue with that.
What kind of motor/head mods was on the car, and What RPM did it hit 24lbs at?

Bone stock evo motor with 272 cams and ARP head studs. That's it.

haven't seen the logs yet to see but peak torque was under 5k.

472@ a dynojet?

They have a DynoMite Dyno, reads like a dyno jet.

layzie12g · 06-05-2008, 12:42 AM

472 pump gas no meth? I just made 430 (dynojet numbers) but the car still wants to misfire on the road. Pulling plugs tomorrow and going from there. Still no afpr. My friends turned out to be a pile.

You are making me want to get on the rollers even more. I got a decent tune right now at about 25psi but I am using meth but you probably already knew that.

Jst4Cyl · 06-05-2008, 02:26 PM

I'm tore between the two damn it.

Anyone have any solid spool up numbers for these turbos on a 2.0 7.8:1cr?

I appologize as I have not read the whole thread but which 2 turbos are you trying to choose between?

chavez408 · 06-05-2008, 06:00 PM

Marti, witch of all the bw turbos is that on the picture you posted up.

layzie12g · 06-05-2008, 09:40 PM

Jst4clyinder I didnt win you over with the talk on the phone? Lol just kidding. Im happy with the 6152r. Its fully spooled (26psi) at 5k. Im happy and my power peaks at 6200 rpm with the stock manifold. Droppinbottom you should bring your car by Pina Motorsports in Kent. Maybe I can get you a deal for an hour or something. (If you dont already know Andre ) I dont remember ever seeing your car around. Well anyways I retuned my car today for 26 psi (no meth) and its running good. 410 whp. Havent got a chance to beat it too much on the street yet thanks to sideways rain.
