Hi, Im in the middle of building a suck through 998 with a gt1752, ive had the car running and driving at 10psi boost, it drives ok but is burning oil badly because of the vaccum in compressor housing sucking oil past seals, now Ive searched around and cant find a carbon seal for the gt17 so ive decided to run a throttle set up in between turbo and inlet to stop vaccum in compressor housing, but im struggling for ideas on how to do it, ive got a rover k series throttle body i was going to use but would like to see some pictures of other peoples set ups and some advice on the job really |

I'm not really sure what you're trying to do. I sounds like you want to build a blow-through but using the setup you have?

the design shows a distinct lack of imagination, talk about starting off with a clean sheet of paper, then not bothering to fucking draw on it,lol On 20th Apr, 2012 Paul S said:

I agree with Will, by the time you’ve gone and added a butterfly, why not just do it properly and make it a blow through.

That picture looks exciting I run a supercharger and I don't care the TB is on the wrong side.

The "suck through" turbos of days gone by did use carbon compressor seals as you obviously know from your original post.

yes , back in the 80's ? i advised on a install on a freinds car , he put a 2nd butterfly in , it worked well .you simply get a throttle cable with a split and two cables coming out of the other side of the split(like on a twin cylinder bike) ,, one goes to the carb, the other to the throttle body , try to have the carb one open a bit more than the throttle body one , so its the body that is controlling the engine , in fact , you may be able to do without the one on the carb all together .
