trying to match turbo for 750-800 hp ???

[dsm's can fly]

my profile is current to what made the last dyno run for this car. but due to a flywheel failure on the brand new motor i now am rebuilding it again. this time i am going with a 6-bolt 2.4 instead of the 2.3. as well i am changing from bc 280 cams to GSC s3 grinds. with weisco hd pistons in 11.1 compression since this is a e-85 car. all other mods in profile should be current. my issue is it seems that the turbo i currently have will not make the goal im looking for of 750-800 whp. since before the flywheel destroyed my motor i was making just a hair over 500 at 28 psi. so my question is a couple fold.

1. will a hx52 put me in the ball park power level (i love the price)

2. will any turbo that makes this kinda power even work in a 2.4 since im rev limited to about 8000 rpms

3. will a dnp t4 manifold fit said turbo (no fans in the way stock radiator)

im a little stumped on this one guys and i would love some help before i sink a ton more money into this car. i looked but could not find a lot of stroker motors with large turbos. most people running these size turbos run destroked or 2.0 motors. neither of which i want to run.

i know this post is kinda long but i wanted to try to answer as many questions as i could up front

I would say the pte6765. There is a local making 700 and change of it. With the high compression and being on a 2.4 i see you having no problem making full boost before 5.5k. I don't have any personal experience with the holeset's so maybe someone with experience can chime in on them.

 

[Black95TSIawd]

I agree with the pte 6765 choice. My buddy just put down 771whp at 29psi in a civic with this turbo.

thanks for the initial feed back so quick i appreciate it . the new pte billet stuff does seem to do well i have a friend running the 6262. i didn't mention it because once upon a time i ran a p trim t67 and the compressor wheel ate the housing in only about 1500 miles. i feel the shaft is to small for the size of the wheels or something.. not sure just kinda left a bad taste in my mouth for pte products. but if someone chimes in that has some serous abuse on one im open to consider it again im sure they have changed a lot in the past few years.

FP HTA GT3586r no doubt! PTE turbos sucks!

11:1 cr is the wrong way, you should be under 8.5:1cr for 800hp you would asking for trouble even 10:1cr with e98

i have never seen the 3586 make 750-800 maybe i missed it does happen im human. but it seems i would be pushing it to the absolute limit trying to. from looking around on FP's site the FP HTA GT3794R Ball Bearing Turbocharger seems to fit the bill. but i cant really find any one running it so no real feed back. at least that i can find.

i dont know were you get that from? this is a e-85 car and i know of at least 5 of my friends locally who run 10:1 at over 25 psi with absolutely no ill effects. and i also have spoken to several big name shops that also run similar compression in there cars. one shop i spoke to actually is running higher than that and makes over 1000 whp. your cr's would be correct for a gas car 100%

 

[ckrell]

i'd like to see the hx52 do it, the lbs./min. is there i guess i'm a holset fan

 

[VETTE_50_TH]

10:1 and 11:1 are completely different. Youll need some type of meth or water injection

 

[ckrell]

apx. how much ppm will you need to get 800hp @ 25psi

 

[VETTE_50_TH]

85-90

 

[paultheninja]

I would stay away from pre. I would look into te hx-52 and Borg warners

have you seen it done? im guessing not if so i stand corrected im not trying to start anything.. i personally know 2 people with 11:1 in there car i have seen them tuned and seen how they respond to it. i would not take it any higher personally however i have still not seen a properly built and tuned 4g63 on e-85 produce knock even at those cr levels or any other undesired outcome. but the point of this thread is turbo not cr. im all ears if someone has had experienced a issue issue with 11:1 cr's first hand, but im not looking for any ones opinion. no offense intended but not the info i am looking for here

thank you,
Jeremy

hx52 probably out DARN

It made 804 or 807 on a evo 4g63 engine.

that is serious power from those size wheels and housings. but evo's do have different combustion chambers and if it was corrected horsepower it could have been greatly inflated, as well as the type of dyno used. it sounds great though and i will defiantly have to have a discussion with fp about it. i just dont jump on when i see a number like that immediately. a lot of people try to push the limit of something one time to get that number but it really cant make it. and in racing you need some consistency.

Devin is running that turbo and running 8s, with a GT3792r your just gonna loose bottom end power, oh and the 4g63 was 8:5.1 compression ratio.

what those guys have done is amazing they hold several records i have followed that car since it had a 16g. the only thing is it is running 41 psi that is a large chunk which it needed to be able to break that record that same power could be achieved i believe (could be wrong some one tell me if i am please!!!) with a larger turbo at lower psi and a smaller a/r which would produce the power just as fast with lower intake temps from the reduction of psi and hopefully the same spool and would carry the power band further with potential for more power if needed. and according to the dyno graph made a little under 700hp

still going to talk to fp about for sure.

just trying to keep the good conversation going thanks for all the input so far

Yes the hx52 has supported that power range more than a few times.

And there are several DSM setups int hat range that are using +10:1 CR. I dont' know why one would use LOWER compression ratio with ethanol. It knocks less than gasoline. It knocks less than RACE gasoline for the most part. Why not have a more efficient setup, if the fuel allows for it ??????

Curt brown and brad gary run 11:1 both running fp3586's. Both 800+ on 2l's running e85. Usually 2.3's don't like higher compression. They both run alumium rod which you're not. I wouldn't go over 9.5:1 being a 2.3-2.4. I'd run 9.5:1 with a fphta88 if I were you. Goodluck to you

here it is. at 41 psi

thats interesting the note about stroker's not seeming to like the compression i cannot really comment on that the only guys i know with strokers have no higher than 10:1 the two i know with 11:1 both have 2.0's do you know any one that had that problem specifically??? i know one 2.4 that has 11.2:1 but is a long rod...

thanks for the chime in, do you know if that turbo would fit under a dnp manifold and what options i have for exhaust housings?

and any idea over spool vs some of these fp and pte's being thrown out here.

dont mean to gang up on you but ive read the holset forums and you seem to know them well

 

[dsm-onster]

Well to get an idea. MBT is affected by stroke. MBT is affected by burn rate. Burn rate is affected by compression ratio.
