Title: How big? Post by: Andy Sykes on September 08, 2012, 08:51:08 am So talking to Russ Fellows yesterday it seams the my 366 bullseye turbo is too small for the Pauter engine I have coming :'( so I need another turbo it's going to be 2.9l 9:1 comp ratio with modular cylinders on meth. So what turbo would you guys go for and what size headers?

It has a billet compressor wheel etc etc. Title: Re: How big? Post by: Andy Sykes on September 08, 2012, 11:11:15 am Hi Matt,
Motor is being built for 800bhp not that I'm going to use that for a while. The s366 is maxed out at 800, so I understand on a flat 4 that's not going to happen due to being inefficent. Russ suggested a S380 he is running a S372 and getting 780bhp and over 700nm torque. Is the HX52 maxed at 900 ? Cheers andy Title: Re: How big? Post by: Fasterbrit on September 08, 2012, 11:17:12 am Yeah, 900 is the limit. Still more than enough for a while ;)
Title: Re: How big? Post by: Andy Sykes on September 08, 2012, 11:20:43 am Yeah, 900 is the limit. Still more than enough for a while ;) Lol too right it's enough so it should make 750 ish on a flat 4? Title: Re: How big? Post by: Fasterbrit on September 08, 2012, 11:26:30 am My HX40 made 638 at only 28psi. The 52 will breeze 750 on a flat four. These turbos are designed to run 45 psi all day long on an artic :)

If you want an 80mm turbo for drag racing use, look at this one: http://www.full-race.com/store/turbos/borgwarner-airwerks/borgwarner-s400sx-80mm-1-25-a-r-t4-turbo.html With this you can probably retain (much of your) current header routing as its also T4 twin-scroll and I wouldn't go larger on the exhaust diameter if it were me. Just match it nicely to the heads. I would stay away from Precision (based) turbo's as I've heard and seen too many fail especially in the larger frames.. Walter Title: Re: How big? Post by: BeetleBug on September 11, 2012, 07:27:29 am Whatever turbo you decide to buy make sure you buy it from a place where you get good service, fast handling and cheap shipping, all of which is getting rarer and rarer these days. I know that http://www.turbosdirect.com/ is the choice for some of the world fastest VW. I have also heard that their customer care is top notch. I cant think of nothing worse than being stuck in the garage due to waiting for parts.

Post by: Andy Sykes on September 11, 2012, 20:19:41 pm Thanks very much for your replies looks like I will be buying Matts HX52, I think I can still use my header that's set up for twin scroll ( need to do a bit more research). I'm sure you will set me straight lol. Waste gate a are twin 38mm from what I've read that will be too big what do you think?
Cheers andy Title: Re: How big? Post by: Shag55 on September 17, 2012, 19:22:52 pm A single TS-44 will be plenty big enough for that motor and turbo. No need for the headach of twins just Y them together.
