Whats the advantages of going twin scroll over single ? Is it because you's have the f22's over there?

 

Thanks Suzuka_Joe for starting this thread...it is awesome!

 

Twin scroll / divided setup should be ideally use a manifold that has paired equal length runners. So that the exhaust pulses are separated so that they all hit the turbo in order without crashing into one another.

This provides an improvement in spool time. However the trade off is that the exhaust side needs to be larger than your typical non-divided exhaust housing in order to flow the same.

For example. My setup is 1.00 a/r and makes 511whp on a 2.0. I have the Full Blown 6265 divided manifold.

The attached photo shows how the exhaust pulses flow out the waste gates. You can see they go back/forth. 1-2-3-4

 

i thought it would be useful

 

That's a great picture! That's amazing how it captured the pulses.

I'm planning on putting a Garrett t3/t4 50 trim .63 ar that I've been running on my Del Sol and use that turbo on my ap1.
Should be a nice quick spooling turbo on the F20, compared to my D16 in the Sol... I get 18psi at like 6k RPMs... And shift at 7.6k.
So its definitely not a fun set up on the street lol.

Can't wait to get working on my s2k! Just need some more money... Lol.

 

Wow thats a fantastic explination thanks grand master khan and a cool pic to go with it

 

Thank guys. You can thank HerecomesBoost for the photo.

 

So this might be a pipe dream but here goes.

I have an 02 ap1 and id like to get ~300whp and ~200wlbs/ft and I know that a SOS stage 1 SC kit does 307whp and 187wlbs/ft but then I have linear power build. So is there a way to run a smallish turbo and keep stock injectors (still have to change fuel pump, run EMS, and boost control im sure) and have a nice quick building curve that doesn't fall off too fast at the top?

Thanks

 

Pfab and a gt3071r. run 9psi and make 350whp and plenty of torque with instaboost

 

thanks Joe

anyone on here recommend a shop to go to in the puget sound area of Washington state?
