HP on Stock head?

[93AWDTalon1]

I was wondering how far power can be taken with the stock 1g intake head with cams?

 

[Spartan302]

Atleast 400+. My head should be back from the machine shop soon. I'm just getting a valve job done. I'll be running hks 272's with a goal of about 375-400hp.

I made 449.8 whp and 400.9 ft lbs with a totally stock head, stock cams (exhaust cam retarded one tooth), stock intake manifold, and ported 1g exhuast manifold with a T3/T4 adaptor plate and GT35 non bb turbo. This was on 27 psi, C16, 12:1 A/f, and stock ecu, 680s, and Evo 8 mas.

Thats really good!

Where you running all this when you ran the 12.1?

I'd hope not

That's 12:1 air/fuel ratio, not 12.1 in the 1/4. I know Sean Ivey went 10.40's on a stock head with HKS 272's.

He was referring to the 12.1 sec 1/4 pass thats his timeslip.

ahhh.... It says 12.1 on the side under his car and his name and stuff.

 

[NOSLO2PT0]

Oh. don't tell anyone I didn't see that

What kind of rpms to the stock cams make power to?

 

[AMS Eric #2]

The 12.1 was on 560 Evo injectors, and a fuel pump that was past its limit and dropping pressure. It was made on 21 psi and not dyno tuned, probibly making about 365-370 at the wheels.

Stock cams and intake manifold will pull to about 6800 if tuned well, then start falling off dramaticly after.

Have any pump gas numbers?

Have any pump gas numbers?

How about 11.50@119 for me on a dinky little fiddy trim? Estimated around 415whp on 93 octane.

 

[psychlow]

A dinky little 50-trim.... funny.

 

[NOSLO2PT0]

Compared to what all these guys have now, yes. 5 yrs ago, a 20G was a race only turbo. Now, you get laughed at if all you have is a 20G. 2 yrs ago, a 50 trim was the limit for a "street" turbo, and the FP Red (60-1), was race only. Now, if you don't have a level Eleventeen turbo on your car, you ain't shit. If you running anything less than the ever popular SCM61/56 Trim/GT35/GT35R, etc. etc. etc. you just ain't keeping up with the game. However, 90% of the people that strapped these 600hp turbos on their cars, still ain't got em out of the 12's yet. I'm still working on my 10 sec. pass on my FP Green, then I'll throw on my FP3065 (yes, I got one too ). Until then, there's no need to upgrade until you have maxed out your current setup, or proven that you know what you are doing.

 

[psychlow]

Yeah - I think it's penis envy or something. If your buddy buys a 50-trim, you must need a GT35R!

Until then, there's no need to upgrade until you have maxed out your current setup, or proven that you know what you are doing.

But there's the key statement - right there.

When I hit the limits of this T04B V-trim I just bought, I'll start looking for something bigger. I don't see that happening any time soon, unless I win the lottery.

 

[lambertvr4]

Ahhh, the good ole days. I remember the "20G is way too big for the street" conversations well. And before I ever grew out of my 16G I wanted way more than a 20G.

Street turbo I've chosen is the 50-trim. "Fun" turbo will be an SC61. Both on strokers.

 

[AMS Eric #2]

Im guessing 380 range with all the stock induction. I havent tried to push it on pump gas because the logging (ALDL) circuit and boost gauge circuit on my ecu went kapoot and Im not able to monitor timing or knock sum. The ecu eventually died totally. Sucks cause I lost my tune on the afc because my ecu was calibrated differently.

What kind of boost are you running?

 

[NOSLO2PT0]

What kind of boost are you running?

That was done on 25psi, 93 octane, middle of august, stock ECU, AFC, MAFT. Nothing special, no standalones, no water injection. Just good tuning and lots of boost
