Ok a while back I did a Dyno at same place and it was 299 rwhp 290 tq with the SL55 Y splitter, Magnecor wires, Denso Iridium plugs and 2 freshly cleaned Green filters on the graph it shows 297 but its cause the Tech selected wrong dyno run from last run. Since then I added the ASP pulleys and threw in my fresh K&N filters and got 311.67 RWHP 314.65 RWTQ on run showing 308.03 it was after I reinstalled my dirty Green filters but I strongly feel if the Green filters were clean the same result would be had as the K&
N. I can't wait for the Tune and Dyno then re-dyno again with the H/E and Johnson I/C pump installed. These are uncorrected numbers and as for conditions look on the graph please.

Congrats on the pulley setup!
How long did you have the pulley's on the car before you dyno'ed? I wonder if the ECU has had a chance to adapt and perhaps you will see a little more of a gain after you have the pulleys on the car and drive it hard for a few hundred miles?

Hey used:

I have to admit, I am a little dispointed in the numbers, as I will be installing mine this weekend and was DEFINITLY hopeing for more gain than that. 3 lbs of boost should have been good for Darn near 50 at the crank. I guess our LITTLE intercoolers just CAN'T handle the added boost, ie HEATfrom my buddy PV=NRT.

Well, I'll let you know my results later next week.

See yeah

Keep the mods comin!!!!

c32used

Honestly since having them installed maybe a few hundred or less miles

c32used

At the crank I heard 40 hp so at the wheel well in my case its like 12 rwhp but 25 rwtq is amazing on just pullies imo. Pretty sure after tune and install of larger heat exchanger and higher capacity intercooler pump it will be a much better difference. I have read in many threads that gains at the wheel average like 15 hp so I am not disappointed.

Unless there is a problem with your current IC pump, the heat exchanger and higher flow pump shouldn't make a huge difference on your first dyno pull before the car is really hot. You'll really see the difference after doing several pulls (your IATs won't increase as quickly, so you'll maintain power).

1FSTAMG

well, there goes my plan for getting pulleys. I can't justify the money for only 12 rwhp and 25 rwtq. I mean seriously, 12 rwhp is simply a cool day vs hot day. If it was a $300-$400 mod then yes I could justify it. But not at the prices everyone wants for a crank pulley.

c32used

I really expect the Reflash to really bring out the pullies true ability the I/C pump and H/E is only to keep the power more consistent thats all thus making the runs more around the same numbers.

jgsx

Sounds good. Yup, the ECU flash really unleashes the full potential. I ran for a while the ASP pulley but stock ECU code, and once I put the code back in, wow.

You're driving a Mercedes Benz AMG model nonetheless, what
do you expect?

Code3 Performance

Well the high prices will be changing very soon. I think the price of every pulley on the market is ridiculous.

c32used

Yes its not Cheap but if its more power you need then it will have to be done thank God for the members turned sponsors Code 3 Performance and LET motorsports for making foward steps to lower the price of HP/TQ for our cars. I bought the pullies 2nd hand so its alot cheaper. Ask everyone who has modded their cars modding a Euro or German car is by no means cheap. the 12 RWHP N 24 RWTQ is pretty good imo at the price I paid. You definitely feel the difference and if I am making low 13s in the quarter stock then the pullies and tune should put me easilly in the mid to high 12s that will make me pretty happy.

P.S The numbers I posted on the dyno runs are uncorrected so it shows lower numbers so 3-4 additional HP/TQ can be assumed for corrected numbers.

^C32USED

who is reflashing your ECU? are you sending it out?

c32used

I got in on group buy on Evotech Tune thru LET and planning on shipping ECU on Monday so maybe a dyno on Friday of next week.

Congratulations on your new hardware. +25 lb.-ft. is certainly enough to feel!
Don’t be discouraged. Know you've seen Vadim’s ODPS results, but just for reference...

I’ve frequently interpreted chassis dyno results with a healthy bit of skepticism because of the myriad variables involved. It’s too bad your dragstrips are closed for the season. Those are the numbers that count, and matter most, IMHO. You were only three tenths from the twelve-second club on your last outing. When you next head out there with your forthcoming tune and HE, you’ll certainly be among the elite quick around here.

Keep after it.

c32used

I am by no means discouraged by the results. Quite impressed actually I know with the Tune I will definitely make the 12s club can't wait til our next outing at the track next season.....based on thr results I feel strongly that I am done modding my car but one never knows
After I get the ECU I will dyno and then in the Spring/Summer after the new I/C pump and H/E are installed. But its the track results that I care most for I will try the filter research again with this setup and I will also try drag tires too Nitto 555R to see if a difference will be made to the times. It should be fun I am also planning am autoX at Road America too in the Spring or Summer. I might go as far as getting and LSD from www.phantomgrip.com if I really want to waste the dough.

Thanks c32used. Don't know what we'd do without 'ya Your honest tests are much appreciated and offer valuable insight to those of us who are considering mods.

I've long been skeptical of aftermarket part manufacturers' claims of HP gains. Renntech and Kleeman want about $3,300 for these things with the ECU tune. Assuming your ASP pulley is similar, it would be hard to justify that kind of price given your results. Maybe you'd get a few more horses with the ECU tune but I doubt you'd come anywhere near the 40 HP they claim.

1FSTAMG

i guess I'm just used to the 03 cobra I had before this. With a blower pulley, tune, catback exhaust and cold air intake i was running 11.7's@118 mph. Stock was 13.3's@109. All those mods total cost me about $900 and gained me 100 RWHP.

c32used

U R welcomed

I am expecting a modest 10-20 RWHP from the Tune..........I am like you and really don't want to spend anywhere near 3k for what I have got so far.....I want to say I spent more on cosmetics then these engine mods I been with this forum over a year and wanted to post info I didn't readilly find in search but as you can tell by the link JTurkel posted started by Vadim well mods effect each car a little different based on stock HP/TQ But after running these pullies for a few days now that to much power increase demands madatory suspension mods well atleast thats how I feel it so far..so a Tune I see now will do it for me...

c32used

For MB $900 might get you used pullies or a discounted tune...

Code3 Performance

$900 will soon get you much more...

Code3 Performance

By the way 1FSTAMG, I know what you mean




And of course, the poster I did for CCW It makes a great desktop background

c32used

Keep it coming I may have to upgrade the suspension Brandon and maybe your good price will help that thought stay alive.

congrats on the pulley set up. how much did you have to pay?
