nismo_lp Posted August 18, 2005 Share Posted August 18, 2005 ... does that happen? reason being that at speeds below say 90ish i can take it to the limiter and dont hit fuel cut.... but at higher speeds i hit what i think is fuel cut way before i get to the red line!?

Doughie Posted August 18, 2005 Share Posted August 18, 2005 it happens because at higher speeds there's more aerodynamic drag (vs. very little at low speed) and therefore more load on the engine and more boost. That and/or cos you're in a higher gear too. Someone will be along soon to explain properly.. Quote Link to comment Share on other sites More sharing options...

Jake Posted August 18, 2005 Share Posted August 18, 2005 At what boost level does this happen? Quote Link to comment Share on other sites More sharing options...
nismo_lp Posted August 18, 2005 Author Share Posted August 18, 2005 if i had a boost gauge id tell u! lol what should i be hitting with just a rear decat? Quote Link to comment Share on other sites More sharing options...
Jake Posted August 18, 2005 Share Posted August 18, 2005 It's irrelevant if you don't have a boost gauge FFS Post again when you have a boost gauge. One that has Peak Hold Quote Link to comment Share on other sites More sharing options...
Clarkey Posted August 18, 2005 Share Posted August 18, 2005 if i had a boost gauge id tell u! lol what should i be hitting with just a rear decat? I'd consider buying a boost gauge before an FCD. Or get both. With cat #2 gone & a aftermarket exhaust .. maybe 0.9 - 1bar (1bar if you're lucky) Cat #1 is the one to get rid of .. ideally both of them.

nismo_lp Posted August 18, 2005 Author Share Posted August 18, 2005 so the fuel cut is currently kicking in at 1 bar???? Im not sure i want to tho too much money on getting performance out of it as i know il end up doing more and more and spend £1000's on a single etc... now ive got a taste for speed i might take the easy option... sell it and find 1 supe thats already had the single fitted!

carl0s Posted August 18, 2005 Share Posted August 18, 2005 I thought this was normal. I only hit 15psi above 90mph, fuel cut comes shortly after. Quote Link to comment Share on other sites More sharing options...
