Thank you sir!

Just simply amazing

Mr.Squeeze

Nice parts list you have there in for results


Whats the power goal for high boost ?

Thank you!

Mr.Squeeze! I wanted to thank you in public for answering all my questions in PMs

For now im looking to make 600 WHP on high boost anything beyond that will be a bonus for me, and 500 WHP on low boost

My external wastegate sping is 10 PSI

SPOHN

Your goals will be meet easily even at wastegate pressure with the 9.5 CR.

Indeed.

I dont want to be the king of the street or break the track record of VHR engines, I just want it to be engineered as is reliable on street but is fast on track.

Mr.Squeeze

No problem man glad to see you going forward with the project


I really think you should upgrade your housings to reach your goal of 600 whp on high boost with 9:5 CR. With the lower compression it's going to take more boost to make 500 plus WHP and to reach 600 WHP I think the turbos will run out of steam and hit a wall. I say this because two car's I know of that are local and built motor TT have yet to hit 600 whp .

Your in Dubai it's hot you don't want to push the turbos to the limit and blow hot air into the engine your better off making more efficient power with bigger housings.

Thats a good point.

Do you mind sharing the spec of build and power of these local guys like what PSI is the max they could go and what CR they have?

I want to go to the limit with these turbos before upgrading. You and I know that we are waiting for GTM to release the T25+ housing for their new manifold so I really dont want to upgrade anything till GTM release the new technology

I tried to explain. Funny part was reading that he would make his goal with no problem.

OP Squeeze has already been down that path. Good advice.

Mr.Squeeze

One car is 10:1 CR at 15 pounds 570-580 whp and the other is 17 PSI 9:1 and around the same power level.Consider this on my build my low boost spring pressure 10:1 CR GT3071 .64 A/R makes 596 whp 14 PSI on a Dynojet. That's Fast intentions 3 inch exhaust. On my higher boost settings I hit a wall of back pressure, with smaller turbos you will run into that wall much sooner than I have.

The T25 plus housings have been out from Garret for a long time now its the manifolds that are needed. At this point it's so late in the year it will most likely be a winter project once the manifolds come out ,the turbos are a pain to get out to swap housings.

You really made me consider going for stage 2 housing and called Sam (As i said in OP "your suggestion will be written on my todo list" ) he said that I dont need the stage 2 housing for my goal. Remember that I have 3" downpipe w/ external wastegate + 3" exhaust system.

He said he will post something here soon with details about turbos and etc
