The ECU tunes are doing more than just raising boost to add HP. There's a few parameters in play, with boost being 1 of them. And as Carl stated, a 20% increase in boost is nothing to sneeze at.

It also says 730 bhp at crank, how do you get that.
We have just had a discussion about octane making hardly any difference.
The same for ignition. All these extras like headers,filters intercoolers do not add horse power they allow more boost to be used! So if you believe the 730 at the crank that's an extra 130 bhp for an extra 4 psi Upping the boost is the only way you will get significant extra BHP. Before you say it I realize a bigger engine will produce more bhp with extra boost than a small one, however there seems to be a lack of maths, more guess work. Was it really only 4 psi more than stock, I find it hard to swallow, 26 psi maybe!
It's a shame I didn't see the crank figure earlier

Hey Sherlock, SGC noted in the video sidebar that he used 17% driveline loss...if you have any questions about that ASK HIM!! But 624 rear wheel horsepower on a Dynojet is what it is. Like I said before, most stock 65's dyno 490-530rwhp on a dynojet...so take it for what its worth. And as i stated before, not sure what tool he is measuring the boost. The one I used could be measuring the boost differently. Maybe on his a stock would measure 16lbs...so knock yourself out figuring out if 6lbs increase in boost is enough to generate 100hp...

Tom, I was chatting to Ricker yesterday and we briefly touched upon Mbworld. His theory was sound8 must be lonely and bored. No matter how often we explain things he comes up with another question or refutes the facts laid out before him.

I mean he just makes stuff up: "We have just had a discussion about octane making hardly any difference." Not one of Tom, BenzORama, Ricker or I said that, for God's sake give it a rest and get a clue.

That's right blame it on SGC, ... I don't know where he gets his figures from
What happened to the precise figures you give, and tell your chum not to keep butting in, I am started to wonder about how he always supports you
What is the standard boost on a CL65, from MB please, how much boost do you run on YOUR CL 65. I know far more about turbo engines than you give me credit for.
I thought we agreed that a crank/flywhhel figure is not possible, remember you said it With your car 100 whp less than SGC an how fast your car is you must be running similar boost.
I think 16 lbs is rather low. I smell a rat.

sound 8

You couldn't explain your way out of a paper bag.

TMC M5

Are you serious??? You seem to have all the answers in your little world..or is it that you gloss over the facts and twist my words left and right. For example, did I ever say my car in its current configuration had 100rwhp less than SGC..yet you draw that conclusion. Look up your own information and ask someone else your inane questions...

I kinda like him. He's like that really, REALLY ugly dog you had as a pet as a young boy. He has bug eyes, looks like a drowned rat, and eats his own poop, but somehow you still let him lick your face.

He's a complete dolt, but somehow entertaining.

Maybe I got carried away..it's called enthusiasm

TMC M5 you carry an incredible amount of info in your head!

All I want to know is a accurate figure for a CL65 boost stock.

How much whp you have.

What boost do YOU run.

Simple!

This is strictly an estimate from experience with charged-vets and I am hardly a pro.

1psi=20-30 rwhp depending on several factors. First 6 psi tend to be very linear as far as HP increase. At the high end of boost (i.e. 30 psi), subtract 20% from the estimate.

Again...not physics just my limited experience. Many variables to consider such as parasitic pressure loss (piping, IC, etc...), cooling efficiency, DR, compressor efficiencies, engine flow, tuning and on and on and on....

SGC

Sorry, I forgot to mention the steroid injected gerbil under the hood that is chasing a piece of delicious cheese that we have on a leash running on top of torque converter to add extra power. My mistake.

Just kidding, the gerbil never took steroids that I am aware of. The numbers are the numbers. The car put down approx. 530 rwhp/ 660 rwtq stock.

TMC M5

Better watch out...that gerbil may have to testify in front of a Senate Committee....

Hi, as TMC M5 won't answer I will ask you.
What boost was your car running to get 530 rwhp in other words stock.
And TMC M5 said you were running 22 psi to get 624 rwhp. Is that correct.
That's an increase of nearly 200rwhp for an extra what......boost..
Thanks.

624-530 = 200 ?!?!?!??

Your math is terrible...

Sound 8 got it to work!

Carl Lassiter

Sound8 really is a sad and pathetic little creature. I tried on other threads, as many of us have, to be civil but he/she's too much of a childlike moron to comprehend a word any of us say. And to top it off his/her laughably testy attitude comes out at a moments notice with the launching of mini tirades.

For the sake of other Brits, remove your location, they must be mortified. Better yet, cry yourself to sleep and take another self-imposed break from the site.

SGC

Not sure of exact stock boost presure, but believe it is around 1.1 to 1.2 bar.

I wish I picked up 200 hp to the wheels. Damn underperforming gerbil.

V12Godspeed

Don't even bother answering him Steve, might as well talk to a brick wall.

sound 8

I purposely put a figure of 200 to get a reaction from TMC M5, but I see he has no backbone, and can't tell me some simple facts about his car.
Usually he can't stop talking about it.

sound 8

Thanks for the info, so I guess your car at 22 psi has an extra 5-6 psi
if stock is about 17 psi. God you would think I'm asking for the code to go nuclear.

BVLDARI

sound 8, can you post some pictures of your cars?

sound 8

Better ask for permission.
I can see certain members saying, there's Sound 8 showing off again.
Sure, but it will be Monday now.
