Just got my milltek....Few questions.

[golfyste]

I agree with prawny with the 2.5" exhaust bein fine on a stage 2

But arnt the agu injectors smaller then tr aum? As they run out of steam at about 250bhp don't they?

This was advised by R-tech (Nick)

AGU running K03s forge actuator,
Forge 007p,
THS front mount,
VR6 maf,
Calibra injectors,
2.75 or 3inch with decat

This set up would see around 250bhp. If the 2.5 would be fine im gutted now as iv just paid for 3inch right through to a 2.5 backbox

A 2.5" system would definatly be fine as prawny said that's what he is runnig with 300bhp and r tech golf when it was runnig 280bhp also had the 2.5 miltek system.

Can I ask why you would go to the effort of getting a full 3" system and then bolting a 2.5" back box on? This would surely create back pressure and slow the exhaust flow 

[jamie1989]

Arh mate not my choice lol He doesnt have a backbox their made up and if I want it a 3inch backbox too then il have to wait until next week. Next week its booked in Rtech again so too late.

Im always in a rush getting things done thats my problem.

It's always the same mate 
Either way that set up will be fine for up to and probably over 300bhp

[jamie1989]

Thats good news 

Im in need of a new rear valance now.

I'm pretty certain Niki is talking about the downpipe in that spec!

Nobody to my knowledge makes a 2.75 or 3'' catback system off the shelf for the mk4, excluding the ebay system from america that has recently come to light.

All Millteks for ko3/s cars are 2.5'', ko4 based milltek catbacks are 2.75''.

AGU injectors are indeed smaller than AUM ones, but the AGU injectors will fuel for 240ish bhp happily enough. The MAF, injectors, and ko3S all run to a limit at about the same point on an AGU.

calibra injectors and VR6 MAF give a little headroom for sure, but overall figures won't be MUCH higher. 250bhp from a ko3S is still very rare, 240 isn't so rare, but 250 isn't often achieved, even with nikis ultra magic mapping skills!

[golfyste]

Yeah but I would like to get the uprated maf and injectors as if it turned out the injectors werner performing as well as they should I would be gutted 

[jamie1989]

We will see next week same spec as mine at his place running watermeth is 260bhp.
Mine is going without.
Chris was runnin near 250bhp an iv gotta beat him lol

Whilst at Rtech Niki an Jim both spoke to the guy who built my exhaust an both agreed that either 2.75 or 3" is needed for maximum flow

i thought stanadard agu injectors were limited to 220,230
