Those of you considering such a large crankshaft pulley should take some time to read about compressor efficiency and read this thread...

Well i saw a Renntech stage 4 that dynoed high 480s rwhp and 520s rwtq then changed the renntech pulley to a ASP 180mm and LET dyno tune and made 531rwhp and 545rwtq and this was on 20 in wheels. On one of my friends cars the same day an 04 e55 with just ASP 180mm and LET dynotune he put down 487rwhp and 525rwtq on 20x11 HRE rear wheels with 295-25-20 tires. Jerry and Wayne from LET said if it was on stock 18s it would have picked up 10+whp & tq on both sides, needless to say LETs tune and ASP 180 pulley do an amazing job together! This car with an Active autowerkes tune we dyno'd before LET flashed there tune on the dyno and it would only dyno 450rwhp they picked up 37rwhp just putting there dynotune on the car!

Yes ofcoarse a heat exchanger an pump upgrade is something needed I would say to run the big pulleys so keep that in mind if you want to do one.

I think as long as you keep an eye on the cooling side and upgrade, who cares if the pulley is at 60% efficiency and you are dyno'ing 30 more hp as long as you have no heating issues?
Would the concern be longevity?

That is my goal.. I was un-able to note any measurable heat increase by going from the 178mm ASP to the 180mm ASP , based on my data log runs.. My track time did increase though..

Also note: That many of the MODS we add can lower boost but increase motor efficiency. So, depending on what your mod plan is, you may end up with a ton of power and still be very efficient..

Do you mean the actual difference in the size of the pulley? Will do, just going off the reported size of our VRP pulleys. I would hope the 180mm pulleys are, in fact, 180mm pulleys. I would also do a before and after dyno to measure those differences for a tuning comparison and BS factor.

Wouldn't the money be better spent on some headers or TB?

I guess, possibly?
The headers I'm looking at are about $2500 for long tubes and with install and follow up tune probably total $3500 or so for about 40-50hp? 180mm and tune would be about $1600 with Xhp? :thinking:

Didn’t they say you can’t run any bigger then 175mm pulley without having drow backs?
I recall evo saying theri 180 bleed boost and was a no go...
Also how many runs can you do in the summer with that thing?
That power gain is beyond impressive if it’s true, but is this the result of 1 hour cooling car before dyno, then an other hour cooling for that one great run you just cannot replicate every time?
IT has to make the power and it has to hold it
Now is this the case here?
If so have you raced other similar modded cars to see the difference best of 3 just to see if the heating issue comes into play
Thanks!

Well when the guys got the LET dynotunes there cars sat before they got on the dyno but i know for sure my friend AL's stage 1(ASP180, and LET tune, K&N Filters, Split Cooling IC setup) 04 E55 did his first pull with his old software from Active autowerkes with the 180mm and did 450rwhp and 520rwtq then within 10 minutes jerry and wayne had there tune ready to install and we ran it again comming up with 488rwhp and 525rwtq. We then were wondering if the airfilters were kind of dirty so we pulled the tubes and ran the car again for a 3 time within 5 minutes of the previous pull this time the rwhp went down like 4 or 5 hp but im sure it was due to haveing the airtubes off and pulling the hot engine heat in. So all in all the car made the power and ran run after run and this is in South Florida and it was in the 70s i would say when he dyno'd.

Also this car i talk about above(04e55) had the ASP 175mm Pulley previously and Active Autowerkes tune and went to the ASP180 and LET tune but we didnt dyno the car with the old 175mm just with the new 180mm. Just between the tunes we gained right at 40rwhp and the top end is AMAZING now.

Here' something I found that was posted a while ago by Vrus.
The E55 is limited to what it can do because of the blower.. Anything more than 15psi and you are just making more heat. S/C is out of its efficiency range. This is why running a pulley any bigger than the 175mm is pointless.

How much boost does the 175mm pulley makes?

I meant ET times reduced and MPH increased! Got me on that one
I am not having any heating issues and run in the Texas heat.. The aux. cooler is perfect for this set up.. You can run lap aftter lap and recover in less than 20 seconds.. I ran without the aux cooler for 3 mponths and did not have heating issues but recovery was real slow. Still ran in the 11`s with pulley and 80mm TB only mods.. Aux. cooler really helps,, I would recommend it even on a stock car..
From what I have seen,,, the LET tune is conservative.. They are able to get a very consistent Air fuel ratio over the full hp range and keep it well in the safe range.. It is real power you can feel in the seat of pants, at the track and on the dyno..

Yeah i have to agree we live in Florida and the pulley has no bad affects as long as you have the cooling mods on your E55. Below are some pictures of our 3 cars from the LET day the silver one is Perrys from the Board the Renntech stg 4.5 the white one is ALs stage 1 and the Tectite Gray is my E55 1st pic with the Brabus 20s i took off then second with my 07+SL style 19s just waiting on the CCWs to come in the mail. If anyone wants either of the rims in the pictures there both for sale.

Also on AL's white E55 we took off the old ASP 175mm and it looks to be the same as the 180mm ASP side by side in comparison, But the seat of the pulley where the belt goes is deeper on the 175mm vs the 180mm. The 180mm is for sure bigger then the old ASP 175 pulley but at first we thought it was the same and were not going to even change it!
