Code3 Intake and K&N filters
Code 3 SC pulley
LET ECU mod

Crank or RWHP. I'm just trying to get an idea as to what's next (I'm hoping this will be enough for now). I see 349hp/333tq, so is it as simple as adding the numbers from each product? I don't know what the LET will provide- anyone know?

There are a lot of factors here, I may be wrong but I am thinking that 349 rwhp seems high. (also depends on your baseline before mods)

I am making close to that (349) with a 185 pully and all the supporting mods....

I would imagine 320-330 range....

but just my 2 cents...

I'm sorry. I meant the baseline of 349/333 from MBUSA's website and I assume those are at the crank.

Brandon's Initial dyno numbers with minimal mods were 331 RWHP with the Supercharger pulley and Intake.

or this is from the original thread page 6:

Car has 130k miles on it. All runs are on 91 octane...

Stock - 303.8/294.2
Pulley only - 324.8/320.9
Pulley + Intake - 337.8/334.5!!!

Gains:
Pulley only - 21rwhp/26.7rwtq
Pulley + Intake - 34rwhp/40.3rwtq!!!

The car is strong as hell with no belt slip. Anyway, enjoy!!!

Thanks-

But the true test will be our own dyno numbers I guess. What I post earlier was a reference, but not necessarily what our cars will have. I need to find a dyno around here and see what I can do once the car is up and running.

For like you, I also have ordered the LET "Jerry" tune, hopefully I can get it all turned around next week as well.

My IC pump finally went out so I'm waiting for a Johnson CM30, then I can send out my ECU to LET.

ah...thanks for the info! I got bored with the thread and the amount of junk being posted on a regular basis that I l havent checked it. For what its worth I guess I was right on the money...go figure.

You guys will like the LET tune.....its a different monster.

How they managed to pull off those stock numbers is beyone me.

Stock - 303.8/294.2

Here is a stock C32 and stock SRT6 that we put on the dyno locally.



I would say that a stock C32 should dyno between 275 - 290whp max.

Depending on the dyno, you should see around 315 - 330whp.

Your mods on the above dyno pulled a 317whp.

This thread has six Dyno runs on two stock C32's. Would choosing a different gear make that big of a difference? Do most people do runs in 3rd or 4th?

P.S. Anyone know any good Dyno shops in the SF Bay Area? Once I get my new mods in, I'd like to get a clearer idea of how much I'm putting out too.

TIA!

With all due respect, no, it isn’t.

Hotrodding is a fickle science. Don’t believe even half of what you read - especially my incoherent diatribes.

This thread from Vadim Fedorovsky, whose technical insight several here regard highly, may be helpful with the baseline and enhanced-boost dynamometer numbers you seek. Although somewhat dated, his data is still entirely applicable.

Please note that when only an OE heat exchanger circuit is in place, once you’re rocking n’ rolling past 2nd gear, any additional boost above stock is actually detrimental to producing horsepower. Soaring IAT’s signal the DME to put the kibosh on spark timing and air/fuel ratios in order to save the motor from destructive detonation. Rightly so, as ~17 PSI, 9:1 CR and 93 octane necessitates a careful balancing act to avoid costly meltdown.

Upgrading the heat exchanger to properly control IAT is imperative when cranking up the boost. Code3’s “pulley only” dyno numbers were recorded with an aftermarket heat exchanger fitted, as Brandon disclosed. If you haven’t already done so, budget for that essential piece of relatively inexpensive hardware so that your other modifications can be properly and fully exploited.

I hear you. I will put it on my list. Now I'll need to find someone to help me install it.

Gramma_Benz

Thank you for that!

I just ordered my larger heat exchanger from LET!
