ASP pullies or not...
hello.
My '03 E55 has around 40tml now and couple '06 upgrades (ic-pump and clutch-pack) and my car is going out of extended-warranty next year.
Im thinking to get ASP pullies and maybe a headers before its time to look other daily...trying to save for '07 Gallardo Spyder
should i be concerned about sc or anything if i do those mods with such high miles on my car? i chance my oils well under 10k miles periods etc. if i blow my motor or something can i chance normal pullies back without my stealer will see it?
Thanks for all information and sorry my bad english

40k miles doesn't seem high but if there are any inherent weaknesses in the engine, the addition of a pulley may help them get noticed sooner.
I understand that warranty issues are different in Europe so you need qualified feedback, not guess work from this side of the pond.
My vote is, save your money, cut your risk and get the Spyder sooner.

Thanks for reply DFW01E55,
I know it has sense to cut risks but still i have one full year to left....a little more power is welcome but, ASP pullies is only something like 1k usd installed that is tempting me.....
btw. you ASP users Is there a REAL SOTP feeling when accelerating in higher speeds or is that heat soak killing the beast alot sooner?
Thanks.

Finn, I've got the ASP pulley only and have had no heat soak issues - zero. In the interest of fairness, I should comment that it is winter and my experience may change in the 38c+ Dallas summer.
Here's a little testimony to the ASP pulley, RennTech is coming out with a larger pulley - it may be larger than ASP (or smaller) but it may very well be a response to the big numbers that come from an ASP.
And yes, SOTP difference is big. When you pick up 80 lbs of torque, it will be noticed.

Thats a pretty bold statement.Do you have any proof that using ASP is doing it the wrong way?I understand your all fired up about getting Renns stuff,but to imply that ASP is'nt the right way is a bit off.

No I don't. Actually, agan it isn't the pulley alone I am against. I just think if you are going to go to an extreme, which the ASP is, then you should also upgrade the peripherals to match it. I have nothing against the ASP pulley, but then where is the support for the ECU? Where is the cooling that is needed? That's all.

I would be curious to see what your car dynos with Renn pulley alone and no Renn ecu.then add the ecu tune and dyno agaon.That would be something I'd be very interested in seeing.

I got ya.I dont think it is extremely needed for either of those 2 items unless you go beyond the pulley,such as headers,cams,etc.

How interested. i could do it. I just want a good dyno shop, first.

Good dyno operator is the key.You need somebody thats not in a hurry to get your car in and out.Make sure the temps are the same for each and every pull.This is the only way to see if the true gains.And yes I have always been very curious to see what you actually gain with the tune on top of the pulley.I will be doing this exact test but not for some time,Im either really busy or when the free time comes I like to be lazy.

I got the ASP pulley and IAT's do rise prety quick - but have yet to have a SC shut down ... I also need to get a chance to go WOT for more than 5 seconds (these cars are too qquick) to see if teh IAT's plateau or if they keep rising into SC shutdown ... need 0-155mph blast to know for sure.
If you ever think of taking the car to the 'ring or track - forget it heatsoak will kill you ...
I am looking at getting a larger heat exchanger built up here with more hopefully double the area E.fifty.5 had one made up in the UAE - but he never gave us the details of the design ...
How about it dude !!!!???
A better pump will also help but larger heatchanger surface area, more water volume and a seperated circuit from the radiatior is a good starting point (i.e. as per Evosport - but instead of using a second heat exchanger replace the OEM one with 1 bigger version.
