Tell me if I'm wrong, but I've heard a number of people say this can damage the front/rear LSD. A garage with a dyno only capable of testing only 2WD cars would drop the fuse and drive shaft so as not to cause damage, I read a while back. They were talking about the R33/R34 I think though.
(edit - I should add: they believed it may cause damage and did not want to take any chances)
standard bottom end for now , T04R sized turbo , 45mm external wastegate , HKS 280 degree cams , 550cc injectors , 100mm thick bar and plate intercooler , Haltech E6K management , I am making 550 hp on a dynapac (hub dyno) at 1.2 bar boost and that also maxes out my injectors (a/f 11.5 ) that is on 98 Ron fuel .
Thats an impressive power figure @ 1.2bar, what's the lag like with the t04 ?. 280 degree exhaust cam must help with spooling it a little quicker. What sort of power you looking for when you have the larger injectors?.
I'm going to a big single, and I'm interested to know what rpm your turbo starts boosting.
on an identical dyno , with the same cams , a car with GT2540's is 400 rpm later to come on boost and has far less midrange . I am making reasonable boost by 3800 rpm. I would like to get 700 hp but I will see what happens
Are the cams your running Stage 1 or Stage 2, I may get get my head machined to take a higher lift cam. I believe that 9.15mm of lift is the max on the standard setup. Have you any experience of the HKS 'Step 2' kit?, it comes with the springs, cam, and adj pulleys.
Do you get that wonderful throaty idle sound, with the cams your running?.
700hp sounds like a good target.
Interesting what you said about the 3540's, I nearly went for these, but ended up buying a t88.
