I just found a calculator for rpm's of the blower..I put in the new # with the 3.125 jackshaft pulley .The rpm's of the blower go to over 60,000 at 6,800 engine rpm's . Max for the blower is 50,000 .If I am wrong correct me Please !!!!!

 

I believe in the latest 'best supercharger' thread (by xxsmallpaulxx, I think), that Forced, the vortech rep said 80000 rpm is the max for it.

 

I may have read it wrong..but I got the link for the calculator from a thread that Foeced posted a reply to and he said it was 50,000 rpms .I'll check the thread you are talking about .And I'll think I'll check Vortech's web site

 

I think your calculations are wrong. I think it puts you at around 54000 and the reported max is 53000 (with optimal performance being at 50000) although Forced stated that you could go higher than that.

I put in the calculator [provided by Force ] 5.73 in. crankshaft pulley ....28 teeth SC cog pulley...32 teeth jackshaft cog pulley....3.12 inch serp pulley...shift point...6,800rpm...and IT came up with....over 60,000rpms

 

Well if that's the case then it's going to boost over 10 psi. My recollection is that when I plugged in the numbers for the regular jackshaft pulley and a 34-tooth cog pulley I got 54000 at 7000 rpms. I see about 10psi with that configuration.

Im going to take it easy on it untill I can get to the tuner on the 9th of July .I will see then and let you know .Thinking of upgrading the bearings this coming winter

 

is the 34 tooth cogger stock???

also, if you do bearing upgardes (did it on my v1, MUCH better) i suggest getting the shell polished.... thas what i wanna have done!!

below is a pic of mine, after a few good wipes of mothers al. polish..... (gave up shortly thereafter)

closer.........


(excuse the crappy pix!)

note: see the score-mark i use for the blower belt??? this is the pint at which it is too tight (and causes excessive compressor noise)

not the best look, but effective!
