New Mods ->Water Test ->Need Help/Advice
Ok my speeds seem to be lower than what I was expecting, alot lower actually;
Old Mods: Riva Stage1 + Exhaust, Rideplate Holes, OPAS B/O's, Sponsons, pretty much it
Lake Temp= 73
E. Temp= 77
New Mods: All above + Riva S3 Charger, 42#Inj., Riva Rear Intake, XS Intercooler, 15/19R prop. . .
Lake Temp= 68
E. Temp= 73
Acceleration felt stronger but again not what I was expecting, RPMs where strong-solid 8150, my analog boost gauge was flickering between 8.5-10#s(never had this problem with lower boost). . .I couldnt find any leaks(water, boost, coolant) of anykind.
Any help and/or advice is appreciated.

Jay, your boost is way low for some reason. At 8100 RPM's i was seeing 11 + PSI of boost with the Riva stage 3 SC a couple of weeks ago.
Are you running a BOV? Did you seal the stock IC blockoff plug with silicone?

You have a boost leak.
Check your air lines. Oh- and the prop may need adjustment to run 8400+rpm's

from what he listed he doesnt have an AM ECU so he needs to be turning 8100 rpms.

STOCK ECU; theres a good chance that its a boost leak somewhere, whats the best way to check for one-soap/water solution???
Im running a hks ssqv bov, yes I sealed the stock i/c blockoff with some silicone . . .

What year rxp? 06 -07 shoot for 8200 peak rpm. 3 blades like the higher rpm. Ask me how I know..
