I know for a fact i havent had 1 customer we have installed the turbo for properly that ever had to send it for service..

sharkbait has blown up quite a few, but he isnt your customer.

mike. post up a 4088R setup on the same ''around about'' boost.

as for HTA 86 failing. or a 6262. um. it happens. every turbo will fail. phil IMO if your looking for 86HP. run the 86. it works well in TS. i see your point but your not pushing the 4088r or a 86 hard enough to hurt anything.
Dan i have NEVER used the 4088 since i have been open on 1 car.. It was OLD TECHNOLOGY 3 years ago..

Will your 30r setup make 750??? sure we can go smaller and gain spool but i like to compare 2 turbos that have about the same output..

I don't agree with some of the companies saying that you need 1.5" runners if you are going to be making over 500-600hp. Hell, the stock manifold has seen 600-700hp quite a few times and has not had a problem.

Honestly, the best thing for spool would be to just do a 1.25" runner manifold with a T3 1.06 HTA3586. That would make 700hp and have amazing spool.

david B did a test. 1.25 runner on his dyno was ideal up till i think 650hp. after that 1.50 runner is best. 650 on his dyno is wonderful for a street car. i do beleave this test came with a little more back pressure though. ''more from the 1.25 then 1.50''

point is i swapped to a garrett with no other changes and the turbo lived a long time. 2 precisions blew in less than 3,000 miles. even precision said i wasnt doing anything wrong.

Everyone always uses Sharkbite as comparison.. we still dont know what was killing his turbos.. It would be a funny coincidence that I have 200 of them out there with few ever failing as i havent sent back even 1 to know for sure yet sharkbit killed 10 of them.. doesnt it seem Odd??

that 30r was for the guy who asked. not you and 700+hp. no it will never do that. if it did i think the compressor wheel would spin right out through the front of the car the 1st time it came close. lol i know its old tech but even again right there your comparing new stuff to old.

find a single scroll hta86 VS twin scroll hta86. with similar mods,boost,fuel

I have a ts 3076r with a full race ss manifold and it hits 30psi at 3600. It an old manifold I had. I was planning on a ts manifold but I've been reading on the quick spool valve and thought about that route. But that's a different topic. Thanks mike for doing all of the comparisons it is nice to know and see results.

I am comparing new to old because i am reading threads about how this OLD TECH is the NEW FUNK in TS.. how good it works etc.. Im just looking for some comparisons is all and playing devils advocate..

Most everyone knows me on here.. I go for whats BEST.. if the TS setup was proven to me to BE THE BEST i would put it on my car i dont care who made it.. I could just call shearer and say " Yo make me a badass TS manifold Dawg ".. And it would be done.. I just cant find enough supporting info that it is THAT MUCH BETTER.. I see they all are dying on the top end and if the spool isnt that much better how can i lose 1000RPM on top and not gain anything in spool.. or better yet how can i lose 1000rpm on top and gain 750rpm of spool.. Still doesnt make sense..

I agree that "eventually" 1.25" runners will be to small, however 80% of the evo community will never be over 700+hp on a DJ. Therefor a 1.25" manifold is more streetable in that case.

If I was building a T4 3586 1.06 to make 800hp sure I would be using a 1.5" manifold but if you are trying to make 800hp most people are not worried about spool or streetability. The bigger the better, the higher the HP...

i dont see people saying they are better for drag racing, they offer better response and streetability.

No problem buddy.. Im not trying to toot my own horn but those who have been on here long enough know that myself like david Buschur who FAR exceeds me in testing like to ALWAYS be on top of what is BEST for our customers cars..

I was the 1st one to start testing the 6262 when NOBODY had any interest.. it was 42r, 42r, 42r or 37R.. Then WHAM we ran some 8s with it in 6 passes and eyes were opened that there is something new on the horizon.. a 62mm turbo running what 75mm turbos run.. Weird..

Well i am just trying to research this TS stuff as we get more involved in road racing and see what its all about..

I dont see the better response.. Drag racing aside.. I see 2 graphs identical..

you know a dyno doesnt show driveability.
