Title: Running 2+ - with just the downpipe and HPFP...
Post by: berg on February 20, 2012, 01:44:26 pm
Was talking to h4rdy about this and I know Janner Sy has mentioend the bare requirements for Revo several times. H4rdy enjoys his car more now without ITG/Twintake and I am considering removing mine - although I love the mid range torque the HPFP supplies on the 2+ map.

So was wondering if you remove the cai and the tbe will the car still perform a fair bit better than Stage 1 with the downpipe, intercooler and hpfp but able to put more of the power down, more of the time as there is no doubt a good CAI doe smake the car very aggressive.

Has anyone got datalogging/dyno results with the above removed? is it a daft idea? ie if you want to scale it back just go to stage 2 or even stage 1?

Any thoughts/opinions...

I have ran mine for a while with the standard airbox on for a bit, for when it goes in for servicing. So just a decat and HPFP.

It felt great with just as much low down and mid range. I could tell it was losing a bit at higher revs though. Maybe 10 - 20 bhp

I think i would rather have stg2+ with a std airbox than stg2 with a CAI, if that makes sense.

hi jon, thanks for that as that was what was wondering. so in terms of wheel hop/spin did you find it a lot more driveable in lower gears?

Why does he prefer it without the cai?

I am paying a visit to W8 Performance tomorrow to have Shark stage 2 software installed.  I have an Evoms intake and a Milltek down pipe with 200 cell sport cat so I will report how it runs.  Although, for 270 quid extra I could buy a set of Autotech internals and go to stage 2+............................... :evilgrin:

Hmm not really any more drivable. There is still 95% as much power and same delivery. The warmer weather this week is helping the traction though  :driver:

I had the intake fitted and went back to the engine cover and find it drives better. I am going shark stage 3 soon and have just had a BCS tbe fitted. Coming from a standard downpipe with the pre cat removed the engine pulls loads harder through the rev range. I think trying to get a car to run a stage 2+ map with the std downpipe you will run into high exhaust gas temps and lose power. Id just switch back to your engine cover and leave your tbe on. Intakes are fine for track days when you are using the power all the time. For normal road use the engine cover is more than satisfactory.

I ran stage 2+ with the std engine cover for a few months, just needed the settings pulling back a bit

I'm running stage 2+ with standard air box at the moment (Pipercross panel filter) . Using B8 T5 F9 with no real issues. I have full TBE with sportscat, S3 intercooler + Autotech HPFP. Prob going to try a CAI at some point to see what difference it makes.
