Ok these are the results for a SLK32 (SRT6)



Blue graph is stock 32, green is what the car dynoed when we got it and red is now.

 

I'm guessing the mods are with the pulley's and CAI?

are these stock configurations comparing headers only?

does this equate to 432 hp at the crank! that's one mean motor you got there. now when will these start showing up at the auto cross tracks?

 

The Green Graph is pulley, tune, exhaust, log headers, and intake.

This is on the SC motor.

 

so just headers on top of the rest added 45whp???? or was there some more tuning involved?

 

Is that with cat's and resonator's deleted or still attached? Also stock mufflers? Which pulley size?
Thanks Nice results if just headers alone. Way more than anyone expected.

 

would the gains for te NA engine be comparable? maybe not? maybe 25 HP?

 

Found most of my answers over on mbworld. Heres a list of the mods. Even has cams and a custom intake. Still don't know what pulley or exhaust mods. This would have to be MB's best shot to get into the 11's.

The list is pretty long...

ECU, pulley, cams, upgraded intercooler with remote reservoir (two pumps), intake, headers, custom exhaust, LSD, brakes, wheels, springs, shocks, cosmetic stuff (grill, antenna, roll bars, wood trim), oil catch can. I think that is pretty much it

 

There was definately tuning involved as I know the customer was having lean issues without a proper tune.

That's the biggest issue with these results. They show gains but there are so many variables changed at once that you really don't know which was responsible for what.

I will say that you will need a tune to run headers and possibly larger injectors depending on the pulley size you have.

So assume if buying headers a tune is necessary, especially on the N/A. The SC can get away with it at lower boost.

Is 45 RWHP feasible with a tune and headers? Absolutely, if the boost is there. On a bone stock car I would expect to see more of 20-25 RWHP. Everything works in harmony, 1+1= how well we tune it.

Seeing the results still leads me to believe they are a worthwhile HP investment, although not the first thing I would do.

As far as HP/$ this rates lower then ECU tune, but much higher then cams. I guess we'll have to go get a set thrown on our N/A for some more numbers to throw around.

 

find a bone stock n/a and srt to put them on to show gains.. and of course put them on your car too so we can see how they effect a modded vehicle.

 

so what is the price on these now?

 

Thanks! I was about to say that is amazing considering the others caused a loss/no change in HP. With proper ECU tune would you say more like 330hp for the green line?

I'm just gonna think out loud here, I have an N/A so these numbers are prob gonna be way different/off but I am just thinking percentage wise. This looks like a 9-10% WHP increase on modified SRT so it would be around a 5-6% WHP increase on a similar modified N/A....TVT 250 puts you around 210WHP so I'm thinking 225ish Whp on the low side?

Would you think it is a good next step after TVT250? If so would that be packageable with an updated ECU tune to account for the headers? 2100ish lol just thinking no pressure =-)... On a side note though my 04 in VA is still bone stock and ill happily put it up for some testing if needed.

 

We will soon be phasing out the Flash ECU tune on our 250 package and it will be replaced with a custom tune, price will be increased by $300.00, but expect about +10 peak HP and a ton more power under the curve. Also this will allow for reflashes at a reduced rate (100-200) when things like headers or cams are added.

This may or may not be a logical step. Headers bolted up to a 4 cat single exhaust may not see all that much gain. You have to remember this car had a very free flowing exhaust. Once we can do our own testing we will have more concrete input.

The only thing one can gether from this graph is that they will make power, how much is hard to say.

 

How much for a custom ecu tune on the NA motor with a low boost SC installed?

 

I think the free flowing exhaust is key, but still the product looks great and will probably just appeal the the racers in the bunch willing to make the exhaust mods needed for improvement. Thanks for having the product ready when we are.

 

Just spoke to Vadim, new price is 1349.00 plus shipping

 

I thought the price was $999 seems it would be cheaper if we went directlt to Vadim

 

That's Vadim's new price.

 

Do you plan to install them provide a baseline HP gain?

The SLK32 VRP used was highly modified and had also had a new dual intake installed at the same time. Hard to tell what were the gains from the headers VS intake.

 

yea i dont see too many sales coming in for these until real numbers can be obtained.. 1350$ is alot of money for guesswork!

 

does that intake fit on the crossfire??? it is like a super intake. it is basically two needswings intakes combined but with more hard tube instead of that rubber stuff
