20 psi

[lppro]

so im pulling the motor and haveing it rebuilt with over sized pistens and a mhg with rebuilt head oh and a custome tube exaust manafold...
so about the 20 psi.. what kind of power should i expect at 20 psi? anyone else running 20psi?

thanks for the help!

 

[Bishop92t]

Depends on the turbo. PSI is not a measurement of power or flow.

 

[lppro]

oh ya sory its the stock turbo (yes i know) im gana get a upgraded one eventually (or when i blow the stock one(=)

 

[ForcedTorque]

(or when i blow the stock one(=)

you mean as soon as you run 20PSI thru the stocker, Right?

 

[cnewingham]

20psi on a stock ct?? not wise

 

[Bishop92t]

I ran 20psi on a stocker for a little while, never dyno'd though. I'd guess in the lower 300's. You're out of it's sweet spot by that point, power gains aren't that great.

 

[lppro]

mabe... lol how long you think it will last at those boost levels? (15-20)

 

[Bishop92t]

Mine lasted a few months before blowing at 20psi. I was interested in finding out how much boost it could handle.

 

[lppro]

Im thinking Im gana be close to 400 at the weels.. with a 40 over bore, completley rebuilt motor/head, mhg,arp bolts, custome exhaust manafold, lipp turbo elbow,hks bov, 3" DP, 3"test pipe, blitz nur spec, hks 3000 pipe, cooleze turbo intake pipe and the k&n intake.. oh and 20 psi(= am i close in my speculations?

 

[Bishop92t]

I'll be surprised if you put down more then 350 to the rear, good luck though Stock turbo just isn't very impressive. An upgraded CT-26 however, is definitely capable of over 400.

even with the 40 over bore?

 

[Bishop92t]

Yeah. I think most people are lucky to put down much over 300 with the stock CT, and the overbore isn't going to make that much of a difference IMO.

 

[robbo185]

i believe it when i see it

 

[lppro]

how much of a defference do you think it will make?

 

[IJ.]

1mm/0.40" overbore will maybe make 1>2 hp difference (not enough to measure accurately on a dyno)

The CT is the bottle neck and won't let the motor make any more hp no matter how big it is.

Listen to Bishop he's actually done it.

 

[CPT Furious]

You're getting confused with what will actually make more power. The built engine gives you the platform, but won't actually make more power until you upgrade the stock turbo. Of course, you can also upgrade the fuel, intercooler, blah-blah-blah...

Please listen to Bishop!

I'd like to see IAT's with a CT @ 20 psi.

 

[Burntz]

20 Psi on a CT is just stupid... lol

If you want more power, you're going to need a bigger turbo.

 

[Dunckel]

400hp isn't as simple as turning up the boost. if it were, i would have been there long ago. it sounds like your doing the right thing by taking the time to build the engine to handle it. but the stock turbo just won't be able to maintain 20psi for long. also, what are you doing about fuel?

I'd like to see IAT's with a CT @ 20 psi.

What IATs? The plastic cage would melt off....
