I finally got round to taking the car up to a rolling road today.

As the Sig says its a Mk1 OCty Vrs, with turbo back exhaust, air filter and dump valve. And a stage one remap.

It ran at 223.4 BHP....we had to keep waiting for it to cool off, which means the intercooler needs to go on.

After running it a few times it went as low as 205, then after cooling back to 223, will the intercooler keep it consistant at 223 ish?

Also, will an air intake rather than a cotton panel filter help?

Iv also had figures around 230 quoted with a stage 2 remap once iv had the intercooler fitted but thats one 7 off what mine is now. I only paid £175 for my map so im wondering if its worth hundreds for a stage 2?

The place where i got the stage one (more BHP) doesnt really do a stage 2, so its other places i have got the quotes ffrom.

Don't know about the other stuff but the general feeling is that a panel filter is better than a CAI for power.

I had a CAI on my remapped 1.8T and compared to the panel filter, it only felt more urgent above 5000 rpm. I reverted back to the panel

FMIC will help keep peak power on for longer, and prevent heatsoak from sapping engine power.

Ill keep the panel on, it seemed to make a big difference when i fitted it.

What about the stage 2 dilema? any ideas?

i wouldnt have thought you would get to much more bhp i would stick with stage 1 and get a front mount on.. you can tend to up the boost with the front mount but with your power figures it may already be at its limit:thumbup:

pic of the graph

Ill get the graph up...prob in the morn now but maybe later.

Is a big turbo the only next step after the fmic?

there are other option to make it amazing and they would be

1. suspension to the best you can

2. lsd

3. port and polish head with equal length manni

and away you go should be good for around the 240 to 245 bhp but will be able to hold its own against cars with more bhp.. its al about the setup

for example i could get a 350bhp car and it is only 350 for 0.1 of a second then 100bhp thereafter

or a 250bhp car that is 250 all the way throught the rev range

what would you want i know what i would want:thumbup:

Hi, I know exacly what you mean, my freind has an impreza which is 300 odd, but it comes all of a sudden then its gone, i assume its got a high figure but doesnt last long.

I cant wait to get the fmic, and get the power all the way through the rev range

I hope that the attach has worked, sorry about the quality, i hope you can read it.

Cheers

It's not worked!

It will be interesting to see if the torque has been compromised for higher bhp figures. For a car with your mods and a generic map the power is quite high.

ill try it again when i get to work

if its APR you got ? just chucking a guess..... there upgrade then to stage 2 is only around £150 and i i found their stage 2 great, it seems happy to eat more fuel but i did notice a difference

i got the fmic and full milltek tho and a jabba induction kit

id say it would also depend if your happy with where you are now tho?

where about in the county are you?

Im in cheshire (crewe), i dont think its an APR one, i didnt ask what it was to be honest, i know it drove well so i handed over the money.

IM happy with what i have, i hope that a fmic will just keep the power curve smooth rather than dipping at the top end.

Torque is 253.7 off the chart...iv tried off two comps but the upload keeps failing...ill try again later.

What is your car running at with the stage 2?

An FMIC will reduce heat soak issues in sustained periods of hard real World driving, but not do much on a dyno, because there's relatively little airflow there. If the car's making 225bhp (makes the sums easy). that's 150kW, and a petrol engine is about 25% efficient, so you have to get rid of about about 450kW in a still air dyno cell: Compare that with an electric fire dissipating 3kW!
