    Thanks, I like the 600rwtq better Click here to enlarge 730lb/ft at 18% DT loss with 2 power mods (tuning/smallish pulley) isn't a bad start. Still the 498rwhp puts this E 13th on the overall dragtimes E55 dyno list (entry was just edited and should be up by tom.), as noted more hardware on the way. Car needs a LSD badly before fall at MIR.

    Thanks Mo.

    Also worth noting 7k indicated is 7k actual in a 55k unlike a M156.

    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.

    Andy : Really Nice work !! That is a very good Number for both Torque & Horsepower , especially with those choke you to death stock exhaust Manifolds. That is what is killing your Horse power after 5750 RPM . Besides the fact the fuel curve went pig rich. I believe the smaller pulley is not an Issue , for street & Strip driving. Your heat soak recovery is much better. We ran a 190 mm driven pulley, years ago , Rear truck Ice box, 4 Row Heat exchanger, & 2 Pumps. We blasted through 2-10 lbs bags of Ice ,every 1/4 mile run. Then had a 45 minute cooling down period , before the next run. We never could set a new record , Torque management Issues !! really Bad, It would pull the Throttle back to 79%. ( You've got that Fixed ) Wish we had that answer back then! As progression goes on I would do the exhaust system first. Then Cams. Tuning and incremental, increases up to this point would be easier to see. And any vaccum ? air leaks would not be an issue , becaues the intake has not been distrubed . imho

    Pat thanks my friend!

    Coming from someone that knows these mills inside and out the comments are greatly appreciated. I'm with you on the smaller pulley theory, more boost = more heat and obviously less performance and consistency especially on the street. I'm more than satisfied with the 178 and may only play around with a larger pulley after the rest of the mods are done and dialed in.

    I also agree with you in that in order to really uncork these motors you have to tune the TCU as well, so much TQ management going on in there, it's a must.

    Next up: TB and Exhaust just like you called it. Click here to enlarge

    Take care bud!

    This mimics my results. 498WHP/600WTQ - ASP pulley, IC pump, filters only. Custom dyno tune. Our dynapack is 1.0cf and reads +/- 3hp local dynojets.

    Really? I've never seen HP or TQ as high with those 2 power mods. Especially Torque. You have to tune the TCU in able to do so, too many TQ limiters in there not too. Please post a graph/video if possible.

    Thanks

    Just checked the list again:

    I don't see your entry Bren, nor anyone with comparable numbers with the same mods or even close to them.

    Thanks
