GT3076R Bolt On Upgrade or GT35

[EVO-00X]

Alltime's car is 2WD so remember the extra power loss through the drivetrain in an AWD is going to make that figure more realistically around the 180kw atw mark on an AWD. You can easily get that without changing cams and without using a big GT35 turbo.

Don't think it would be quite that low Rob....215-220awkw more likely.
I'm not sure you'd lose over 60kw through a transfer and rear diff.

Rallyant: Boost was 22psi.

Yeah you're right Benny, I jumped the gun and was roughly estimating the loss of power from the crank lol :lol: Its too difficult to ascertain really as the difference cant actually be measured as a definite number as each car can have a completely different drivetrain setup to the next and different dyno's read different results. The only thing we know for certain is that an AWD setup loses more than RWD, which loses more than FWD. You will lose power through an AWD box, LSD, torque converter, driveshaft and rear diff (extra gears, rotating masses etc). This is one topic where there's no definite %, there's no definite HP figure, just estimates lol :lol:

To tell you the truth, I think it was JSTYLE's manifold design which caused the turbo to lag so hard.

I get 20psi by 4300 rpm, and I dont consider it laggy- at all. Its so streetable, its almost too streetable. I'm even thinking about getting a larger exhaust housing, i'm sure I could handle full boost a few hundred rpm's later! That, or go for a larger turbo perhaps??

lag is a state of mind

what turbo are you running now?

 

[alltime01]

What fuel is this on? 35psi

35psi??

that was with optimax 100. most dynos vary in out put but 124mph down the 1/4 doesn't lie... :twisted:

GT30R, .63 A/R

 

[BobWrinkle]

isn't optimax 100 ethanol based, i.e its pitting your alloy head??

 

[JSTYLE]

Ive had a Garrett GT35R .82 AR rear end. It was a pretty laggy turbo in my opinion.. i still think dre's turbo is also laggy as...

If your after sheer power and dont care about spool time then go ahead and get urself a GT35R.

But if you want response then go for some sort of hybrid mitsubishi turbo.. i have a Big 16g in my EVO lancer which powers it to mid 12 second times at around 16psi.... its soo zippy that it isnt funny and its fast for what it is..

My mate has a GSR that runs 11.2 in his GSR 1.8 and its still running a hybrid factory mitsubishi turbo... makes 272kw @ 27psi...

Not bad for a stock rear turbo housing and stock factory manifold...

[CLuTZ]

Lag can be increased or decreased by the design of your exhaust manifold, that manifold you made for your turbo was pretty average....

I dont find my turbo laggy at all, it makes useable boost well before it reaches full boost!

Instead of a short runner manifold which im using now if you used something like this it would spool up alot quicker

 

[matress]

bit off topic, but that is one of the sexiest evo's going around!

im not sure about the pitting.. but its only 5% ethanol that doesn't worry me too much..

what about my manifold?..

 

[BobWrinkle]

what is the big silver thing hanging off the passenger side of the manifold?

Another turbo or a bov or sumthing?

external wastegate

u (tharaka) said what i was thinking

 

[BobWrinkle]

i thought bovs were external wastegates?

 

[bazeng]

no, a blow of valve goes on the inlet side of the engine.. it vents the pressure caused when the throttle is closed

wastegates / external wastegates are located on the exhaust side of an engine, located before the turbine (turbo exhaust wheel), it bypasses exhaust to the turbo in order to regulate boost..

external wastegates are just a bigger / more controllable wastegate (in comparison to internal wastegates)

 

[BobWrinkle]

so how does it know when to open and close? or is it a pressure thing?

Any info plz? Damn all this time i thought people were just taling about bovs when they were tlaking about e/w's
