Dear guys,

My H22a turbo made a 366 Whp on pump gas @12 Psi,

how much hp can we dig around on pump gas with T3 .63 A/R and if i will change the housing to a T3.82 A/R on witch RPM dose it work?
Now its spooling at 3500 RPM, my problem that my rive limit is 7800 RPM,
No port works head & intake are OEM.....

All we can say is that power will shift to a higher rpm level, and will reach maximum pressure a few hundred rpms later.

You'll need to redyno to answer your question with any accuracy, however

nice turbo!

I would run the smaller exhaust housing, my 62mm made 390whp at 10psi on e85 so I would expect more from your 67. Also you can rev alittle higher.

Dude i am using pump gas no E85 bro....

What is your setups?

tagperformance

E85 is pump gas, but not as many stations across the country as normal pump gas. I'd get a bigger a/r turbine housing, pick up a sp quick spool valve and solenoid kit. you would be able to take that .82 a/r and turn it into a .41 a/r and pick up power and torque and reduce spool time at the same psi that you made 366hp at.

ProPerformance

Get a bettter intercooler and rev it higher.

Thank's guy for the tips....

LOL. e85 is NOT pumpagas.


Labeling it as such is misleading and retarded.



OP: The 82 will BARELY affect spool onthe H motor. When you Up the boost the motor WILL make better power up top as well.. Its not a b16.. You have another half liter of displacement working for you ;O).

I have some vids and sheets but just dont feel like digging them up. The .82 will "shift" power "up" as Shodan said... But on the H it will also help it make power up top. I run a T4 .81 housing and wish I would have gone in the 1.0 range, but I made the power i weanted so Im not gong to F with it.


My car (H22 as well) on a 67mm wheel makes 520 WHP/380 TQ on pump 92 at 17 PSI if that helps answer any questions. The motor is fully built (Head too) but STOCK JDM cams in it and it made 750 WHP and 575 TQ at 35 PSI falling to 32 up top (Probably partially die to the 10 pound springs in the gates, and definately due to the compressor maxxed, but I think a bigger ex housing would have helped it hold power out up top.


EDIT: By the way, since someone thinks your intercooler is an issue, and is wrong.....Im using an XS power FMIC (3.5" x 12 core) tha tI put custom backdoor tanks on and it works fine. I was really suprised at IATs. The never got past 80 degrees F at the top of the 750 pulls. 20 degrees above ambiet is what I saw, Not bad. Intake was cool to the touch at the end of the pulls. IATS dipped into the 70s (62 degree day), then got to 80 at the top. never more.

hussain-vtec

Thanks Brother that's really Helps....

hussain-vtec

Bro With your T4 .81 housing on witch RPM you will gain boost?
And What is your RPM Rive Limit?

Because one of my friend Have a T4 .88 housing that I can take,
But the Question is on witch RPM It Will gain boost on a h22a.

Glad to help.

Remember, My .81 T4 Turbine housing is "bigger" volume wise than your T3 .82. MORE gas can get through it. And IMO its still too small. The .82 on that turbo will still be a mean SOB and help hold a nice TQ curve when you get UP in boost/power levels.

Search the high HP H thread, my most recent dyno sheet is in there ;O)

ProPerformance

Have you ever thought that the reason you losing boost up top is because of you intercooler, or it could be the reason you took you 35 psi to make 750whp?

extralargenog

ughhhh. No. The turbo is done at 35 PSI. DO you know how to read a compressor map? Its out of gas right where it should be. 61mm did the exact same thing when maxxed. Thios setup at 66o didnt fall off, which is more than the 61mm made. The turbo is maxxed. Now Im not saying I COULDNT USE a better intercooler, Im saying I dont really NEED one.

A T04ZR making 750 at 35 PSI is about as good as its going to get :O)

I guess diffrent strokes for diffrent folks. I would rather make same horse power on less boost by having a more efficient setup. Call it a poor choose of intercooler or turbo I just don't want to beat on something that hard when there are better options.

extralargenog

iTrader: (1)

You obviously dont get it... The intercooler isnt the restriction genius, the turbo is making the power it should at the pressure level it should.... Untill the compressor is maxxed out. Beat? Hardly. Lookup a compressor map for a T04ZR and you tell me my setup could be more efficient.... ;O)

I dont know how to make it any simpler, or nicer.

The setup is efficient as **** or it wouldnt be making the power its making at the boost its making it at. I wouldnt make the "same" power at "less" boost.


750 WHP on an old school 67mm wheel and an S cover at 35 PSI is hardly inefficient. My power goal was only 700 (not to mention I got a BRAND NEW Garret T04ZR in the box dual ball bearing and all for 700 bux ;O) ). It made that at 31 PSI....We decided to see what it would make at 35, which netted 750 and change.

Nevermind, this is HT I almost forgot where I was.

ProPerformance

If I don't get it then how did I make almost the same power on a old school 67 T3 as you did and was only at 26psi. I must be getting something. Like I said I own a dyno so I will be doing some back to backresults this weekend to end this argument,but you just keep posting on ht and ill get some real numbers.

Real enough for you? (please excuse the wheelspin)


750 (**** even 700) at 26 pounds on a T3/67 HO? Ughhh Ok, rightttttt..... ****, I wanna dyno my car on your "real" dyno. Looks like my powerband sucks, Stock cams dont work, and you cant make 35 PSI on 10 pound springs eh??? (although honestly the springs MAY have helped it hold up top, as would have a bigger ex housing, regardless THE COMPRESSOR IS MAXXED do you get that?) - like I said, my setup is FAR from inneficient son.

ProPerformance

I know stock cams don't work that's one think we can agree on. We have a dynojet 224x and dyno numbers are diffrent from one to another.

In the end this is pointless. You are just as hard headed as I am. Good luck with your setup.

Hard headed yes, dyno numbers from one 224x to another being different significantly? No. They are VERY consistent.

this is on a 224x by the way, on STOCK JDM H22 cams.

ProPerformance

We have another dynojet less than 70 miles from our shop and get anywhere from 15 all the way up to 43 hp numbers diffrence on the same car. Proof in the pudding.

extralargenog

iTrader: (1)

We have another 224x 20 miles away, its about 5-10 WHP different at 550 ish WHP

Another thats BARELY more than that, same day, same car, same boost. Same everything.

Reason being we were suspect of some dynapack readings being VERY friendly compared to the 224s so we ran a car on a few local dynos.


VERY consistent.


Anyways... Your pudding is suspect. Troll on.


I am my own disinterest in engaging any further OP: goodluck :O)

Where do you get e85 from? out of a pump!. Unless u live on a farm or some kind of refinery plant and some how make your own fuel. Many people call it pump gas and we all know it not the same as gas so stop being so freakin ****. The op is looking for ways to make the car spool sooner and i gave him one there are numerous ways to get the turbo to spool sooner, and which way shall you choose to be cost effective or efficient?. I'm am also a h22a owner and f20b owner.

roadracer4life

here was our ebay VS precision intercooler comparo.. nothing was changed except we turned down the boost duty cycle with the precision intercooler too keep the boost closer to the same as with the ebay unit..



runs #40 and 44 were with the ebay unit at about 28-29psi

runs #7 and 8 were with the precision intercooler also on about 28-29 psi.. i can try and dig up the aem data logs if you would like but the AIT sensors dont react quick enough to notice if there was an actual air temp difference.. but its a moot point because who cares what the ait is if the car is actually making more power..
