bump again

At what point is a 4bar fpr usefull? ie is it stilll worth putting on with a remap or is it only worth it when you are going for 300hp plus?

thanks

Hi guys. Funny enuf I just logged on to try and find the part number for a 4 bar regulator. Cheers! [:D] As I understand it, it allows the fuel pressure to get to 4 bar. I am planning a Revo remap. Stage 1 doesn't need the extra fuel but stage 2 does. Other essentials for stage 2 are a good freeflow exhaust and an air induction kit. The regulator wont do anything to a standard engine. You need the remap to make use of the extra pressure. If u are fitting it yourself be aware that the fuel lines are under high pressure. If you pull out the fuse for the fuel pump and start the car it will use the fuel in the lines and make it safe to remove the regulator without hosing petrol over your face/engine/innocent bystanders.

How much power does a revo stage 2 get you?

I have a had a remap, probably producing about 200hp, i dont think you need a 4 bar fpr for that, anybody know for certain?

I have seen a few claims of around 255 bhp for the stage 2 though Revo doesn't give figures on their site. I had a stage 1 on an otherwise standard engine and got 207bhp on the rollers so if you consider that you need a good exhaust, air filter and the regulator and they recommend a decat downpipe and uprated dump valve, 255bhp should be close

To give you some idea of how the re-maps work here goes from experience on my own car.

Remap and DV only first RR ever for me - 166bhp and 220lbft

Remap - CAI - Cat Back - DV - TIP - No reading car was jumping all over the rollers and AmD go scared and did not want to run my car.

Remap - CAI - Turbo Back decat - DV - TIP - 227bhp - 260lbft(running very high octane fuel and boost adjusted via lemmiwinks)

Remap - CAI - Turbo Back decat - DV TIP - FMIC - 227bhp - 240lbft standard bp ultimate

I have always felt my top end to midrange felt like it could give more so have been considering the 4 bar thinking this may help so anybody out there with an opinion ??

The vacuum pipe on your fpr is in good nick isnt it ? Just to make sure your fpr is supplying 3bar.

yep it is and the engine is running spot on with fueling just wondered if fitting would help let the map run more freely so to speak.

P.S. Only fault code my engine ever gets is either overboost or cat below threshold no poo sherlock there aint one !!

is yours an AGU ?

*Edited* Just read that you have an AUM.[:$].
I recon that from the stage you are at the only way to get more power would be to increase your boost
level or the way it is delivered.Does yours hold 1 bar all the way ? Maybe experimenting with boost controllers [;)]
