Yep. New 8AN line to the rail, 6AN return lines, and at the suggestion of Rob from Needswings, I used the OEM supply hardline as the new return line to the tank. It wasn't too bad. Installing the AN hose ends was more difficult that I expected.

Braided stainless hose and fittings can be pretty expensive. I was fortunate to get almost everything for free thanks to Russell Performance and Redhorse Performance through my drag racing sponsorship from The Contingency Connection.

I am impressed!! You have done a good service here with your info and input but I hope to have good AFRs without the fuel line mod. I'd like to be able to do it with just the AEM regulator and SL55 pump, of course I'm only running the 181 and 70mm stacked setup, not as radical as yours. If I have to, the injectors would be next. I don't need the fastest CF out there, I'll settle for just a very quick one. Congrats on getting things worked out.

I feel like we need to bring the weight question to closure. I usually use cars.msn.com for baisc specs info. That site lists the following weights:

2003 (my year) SLK32 AMG 3220 lb
2005 ( 1st year) SRT6 coupe 3240 lb
2005 ( 1st year) SRT6 roadster 3328 lb

Do you have different information?

Re: STACKED PULLEYS RESULTS! DYNO and 1/4 MILE!

I put my car on Longacre scales and had my car corner balanced. It weighs 3292 with me in the drivers seat. It's lighter than stock but not by a lot. The gentleman that races a SLK in my area swears his weighs 3400 to 3500. Now I know better.

Re: STACKED PULLEYS RESULTS! DYNO and 1/4 MILE!

A question for boostmonkey. Have you found a difference between the fuel pressure at the regulator and the FP at the rail with engine running? Where do you have it set to 66, at the rail or at the regulator?

Matt
One more question for you
I looked at all the charts and they are great! But I was wondering if you know the max rpm are superchargers can spin?
I ordered a 65mm pulley to stack on my 178 & a Killer Chiller kit, I am going to put the reservoir were the
exhaust res was & have a small expansion tank under the hood.
Thanks

There are no reciprocating parts like the engine so I don''t think it will be a hard "max" rpm. Rather, more time at higher RPMs will put more wear and tear on it. We don't have a known, history of supercharger failures thankfully.

Re: STACKED PULLEYS RESULTS! DYNO and 1/4 MILE!

I think the heating and cooling cycles are the biggest worry.
Like Matt said - we don't hear of SC failures...I don't think I've heard of one yet....(in my short 2 years).
Note: when you speak of 16k rpm - that's the direct driven 5 lobe rotor...the Teflon coated 3 lobe rotor is spinning at 5/3x16k = 27k rpm....

Re: STACKED PULLEYS RESULTS! DYNO and 1/4 MILE!

Hey boostmonkey, I may have missed it, what size width tire/etc are you using?

Do you think having a lot better hookup/traction will help your 1/4?

My drag tires are 255/50/16 Mickey Thompson ET Street Radials. They hook great at 16 psi.

On the street I am running 255/40/17 Dunlop Z1 Star Specs at 33 psi. I am thinking about switching back to the OEM size 245/40/17 for the next set though to avoid fender rubbing (it is very close). I will probably be switching to BFG Rivals for the street later this year.

Ah okay, I plan to roll the fenders and have 285s on the back and 245s/255s on the front. I will also be using Pilot Sports Cups and Super Sports

rolling the fenders won't give you enough room to run a 285 on a slk sorry. with perfect offsets and rolled fenders you might can get a 275 in there buts thats about it
