Boost(psi) Related Question??

SL
SRI/TMIC/BPV(blue)/MSCB
Stock BC
Max boost in 4th running through the gears 18-19 falls off to about 16-17 right at about 5900-6000
 
hmm the inlet pipe might help, too bad the ATP sucks had to return it.... Hoping my pump will help if it ever gets here. Im intrested in rontonkin's set up with no drop off or FC and stock pump.

So far rontonkin and laloosh both hold boost. Everyone else falls off. Weird. makes no sense.

Chris doesn't count. Apparently his car didn't get the memo that its an MS3 and that its not supposed to run right with mods and no tune.......

Well hell i dont know how but my 24 spike hold 20 pulls had no fall off up till 6k power or boost wise. I should shut up though cause my car has been in ICU ever since........
 
Ouch! werent you sure of a boost leak?

I'm pretty sure those back to back 290 dynos i did created most of the leaks. the 278 dynos i did before those were only spike 21 hole 17-18. Honestly my car was running SO beautiful till after the dyno.......

Interesting what’s happening with all these MS3's early on many thought 300WHP was just around the corner (including me) now I find myself looking at turbos lol

My goal was 330whp, but if i have to go bigger turbo might as well shoot for 400 lol

ok! back to topic so chris holds 19 on the stock BC and has the 3.5 TMcore i hold 17 all day with my 2.75 TMcore so what we need a 5" lol....
 
rontokin with the fmic and the atpinlet 19-20 all the way no drop off....hmmm

Edit:makes me think if chris did a fmic he might hold 21+ ???

yeah 4th gear it holds right at 19-20psi and 5th and 6th it spikes to 22psi and holds at 20psi not cut and power to redline. We have been in the low 30's and upper 20's in the mornings. I think i am going to back it down to around 17-18psi till i get my fuel pump in just to be safe but for now everything runs great! i am scared to get a DP because thats the one mod i don't have and i have no fuel cut.

nah he already got all the increased boost he's gonna get from taking off the stock top mount. He's need a Bc at this point. I'd lend him mine but his punk ass doesn't want to come pick it up cause he's lazy and good for nothing.

I could see me and chris getting into all sorts of trouble if I lived up there. LOL

So yeah how about my 15psi at 6k. (hand)
