Do any one know how much HP will our 3.3 turbo's gain at 1 bar boost and no cat .

Stock 92 turbo is 320 HP. does anyone have dyno tests ?

Metal Guru

I've heard 10-15 hp per point of boost, so maybe 350-360...

heliolps2

Wow... that's a good gain,

Thank you

I suggest you at a minimum inspect the diaphragm on your wastegate and have the car dyno tuned if you make this change. You can see boost creep and if you exceed 1.2 bar I believe is the point where the fuel pumps cut out. Not fun.

If you want more sound it is fun to gut the WG cat the car roars at WOT.

Metal Guru

Also, the WUR diaphragm should be heavier since the boost pressure is seen there too. Brian Leask can install a heavier one for you.

Hey gentleman

I did have a little boost creep as you said, I turned the boost sense I have a manual boost valve located in the engine compartment nicely tucked under the intercooler, I was also told that running to much boost can harm the EZ 69 ICU, I don't how of that is true....

In the past in my old 3.3 turbo i did blow my WUR diaphragm running 1.2 bar boost, But I was doing alot of DE's and autocross. I had Larry from CIS install a heavier diaphragm. But now I don't drive this car that hard, Maybe W.O.T for a few seconds at best. Once the WUR needs rebuilding I will send it Brian,

Brian is a great guy, I stopped by his home back in 2012.

My old 3.3 turbo had a straight pipe on the WG, It sounded great. Whats the best way to gut tha WG cat, I was thinking of gutting while it attached to the car, After removing the tail pipe of course.

Would I use a drill ? and what kind of drill bit would I use ? Or would chisel it out with a hammer ? I would have a vacuum sucking the stuff out while drill. Good Idea ? your thoughts please

Wait......You mean these cars have cats...?

I purchased a replacement used and gutted it using a hammer and chisel. I don't think it is something you would want to do while in the car. There are also aftermarket pipes sold by companies like Fabspeed.

Does anyone have a WG Cat they want to sell or give away ?

You Need Fuel, Get Euro Fuel Lines & Injectors, Might be Hard to Get, Then You can Go 1.1-1.2 Bar.
I Know, Trust Me I Made Huge Power On a CIS 92, & I was Told Those 2 Items were not a Factor, WRONG, Was getting Lean at 4700, Put them in & Made Music.... Huge Improvement !!

I Had Every Thing You Can Possible Done To a Stock Motor & A Garrett GTR35 Turbo.

Not sure how to say this without inciting an argument. No insult intended. Can you please explain what was done? I find those numbers a bit ambitious. I only trust Mustang dynos as they don't allow the operator to play with the load as this does which can change numbers considerably to make it look far better than the numbers are. Most people are upset when their car is tested on a mustang.

On a stock engine anything over 1 bar even with new injectors or fuel lines can be disastrous. I have seen countless people try this and only ended up with their heads lifting. I hate to say it but CIS is limited and the numbers you posted are just not possible unless you go with a better injection system and stand alone ecu.

The maximum you can safely run on CIS without some type of modified fuel head (which doesn't exist) on a 3.3 is 350 to the wheels. Anything over that takes a lot of effort and expense. You just can't flow enough fuel through a CIS head to make these kind of numbers irrespective of fuel line size or injectors. They also claim a 25% drivetrain loss which is ludicrous would put you at 550 BHP and nearly 625 ft pounds of torque at the engine. I hate to say it it just isn't happening on CIS.

I Get It, Nobody believed Me, But It's Real & Only 15psi, It was the Garrett turbo that spooled so fast that did it, It would just take Fuel fast.

Like I Said Everything was done, 2 fuel pumps, warm up regular & Fuel head both done 3 Times, Headers, No Cat, air Intake, Etc, We kept running out of Fuel, Dawes MS Helped Me, Everyone from coast to coast was called, Fuel Lines & Injectors did it, I spent 2 Years on this car I'm Certain, I used to work with Andial before they Closed, I've done a Lot of builds, This car kept up with my Modded 993tt, Lambos, Very Fast & Shot Huge Fireballs, I'm still trying to buy it Back...

Not gonna go into the Dyno Sheet, Or Debate the Power, That wasn't My Point, If You do those 2 things It will help the fuel to 6500, That's my point, I Think The Injectors ended in 0111(not sure), They Are NOT 3.6 Injectors for Sure, Every Car I Knew of Ran Lean at 5000-5500.

I Sold a Car to a Guy That has a Andial 930 CIS Made 465 Crank.
