Hi
I've had Revo for 5 days now and I love it! :laugh:...But its not enough now :sad:.. I must have more :evil:...
Looking on the Revo site they do a Stage 2 map to compliment a performance filter and exhaust. In theory I currently have 255bhp/285ft-lbs. It states with the stage 2, exhaust & filter I could be pushing upto another 15% which would be 292bhp/327ft-lbs (I wont go all shy when I see an ed30 then :wink: )
Can anyone tell me if this is a load of hype or quite realistic
Has anyone had any experience with having a Milltek and dealer warranty, do they have a problem with it?
Has anyone had the above done?
Thanks
-
Can't personally comment on the remaps, but the Milltek, especially if it is cat-back, are generally accepted as having no detrimental effect on the warranty.
-
Extremely unlikely for a Milltek to affect warranty. Those Revo figures are a tad optimistic but a Hi-flow+Downpipe Milltek exhaust coupled with air intake mods etc will complement a remap and add power. Without a remap the Milltek will only add about 5 bhp maximum. Throttle response is noticeably improved too.
I have a Hi-Flow+Downpipe Milltek plus Carbonio air intake plus Neuspeed turbo discharge and charge pipes plus Forge DV etc etc with Revo Stage1 and for road use I simply don't feel the need for Stage2 even though it would only cost me £50 to upgrade. Stage2 is said to be more aggressive.
-
I plan to get this done soon-ish... so you reckon an extra 5BHP gain? TBH I am happy with the power of the Golf but I really am keen to improve it's breathing to squeeze every last drop out of the engine... plus I like the sound of the Milltek's... although not sure if I heard resonated or non-resonated....

....5 bhp absolute max and not guaranteed but exhaust efficiency and fine music guaranteed. Not a big difference between Non-Resonated and Resonated - Both quite subtle but the sound matures with mileage. The car is still quiet at low revs through town etc.

Sounds like I probably won't have a problem with warranty so I might just get the Hi Flow Cat/downpipe.
After checking with Revo, the 15% increase in power with stage 2 is 15% of the increase (55bhp), not 15% of the total (255bhp) as I said earlier. So I guess with a filter, Milltek and stage 2 you would be looking at around 270bhp
RedRobin, I'm also thinking of the Neuspeed turbo discharge adapter/pipe. What difference did you find with this fitted, did you feel any increase in power?
TT, as you know all :wink: do you know the reason why their is a small restrictive chamber placed on the discharge side of the turbo and not a straight flow path like the Neuspeed or Oettinger adapter?

....Correct. A ram style air intake (with aftermarket flat panel filter in stock box) would be more efficient than just a change of filter. ITG filters considered among the best.
RedRobin, I'm also thinking of the Neuspeed turbo discharge adapter/pipe. What difference did you find with this fitted, did you feel any increase in power?
....I had both Neuspeed Discharge and Charge pipes together with SAMCO silicon hose connections and Forge DV all installed in the same session. There's always a placebo effect and it's tricky to assess exactly what the differences are but throttle response is totally instant and the car responds and revs very freely. I haven't dyno'd her since to see if any power increase but the torque is impressive. I don't need to use as high revs as I did before. Subtle and very enjoyable increase in turbo spool sound on lifting off throttle. The Forge DV is reputed to hold boost longer but who knows?

Sorry, can't help you. Though it could be the integrated diverter valve, as opposed to the remote diverter valve on the Ed30 and S3.

The OEM inlet is a ram style feed. It also uses bypass technology too! :wink:

Nice Capri on the other ramp! :drool:
-
I wondered how long it would take someone to comment on that Capri :smiley:
My mistake - I meant to write an aftermarket ram intake, such as Carbonio.

Well, it would have been rude not to! Even though this is a place where we (quite rightly) hail the mighty Golf, I've always had a soft spot for the Capri, having owned three, and worked on many, many more.
BTW, what was the spec of that one on the ramps?

Ah, OK, no worries. :smiley:
Yours does look lush, but weren't you thinking of selling it? :huh:

Re the Capri, I have no idea about its spec - I know nothing about Capris except that I never much liked them.
Re the Carbonio, Gosh! You've got the memory of a woman! Yes I did toy with the idea of changing it for an EVOMS air intake but was greatly put off by how I found Regal Autosport to be and they are the sole UK distributors. Also, I had a brief ride in a Skoda VRS with it fitted and didn't like the very rough noise. Also, if EVOMS' power gains are true, I really don't want more power through my front wheels - I find my car very well balanced as it is.

Ahh, so you never experienced the "compulsory tuning requirement" for Capris, then - a bag of builders cement in the boot :wink:, to help with rear end traction! :evil: In all honesty, if you were to examine the Capri with your head rather than heart, then they really were the epitomy of the "Dagenham dustbin", with aweful handling, and very agricultural mechanicals - but those "qualities" also made them a fun and entertaining drive, and they were very easy to maintain.

ROTFLMAO
Actually, my mrs seems to think I have the memory of a sieve! :undecided:

Ahh, so you still have it then? BTW, does the Carbonio use the "bypass" function, similar to the OEM ??

OK, it is slightly confusing to explain! When you are using "ram air" for the airbox, high vehicle speeds with very low engine speeds can cause over pressurisation of the airbox. The bypass fuction allows some of this excess air flow to "bleed" away.
In the standard Golf air inlet, on the bottom edge (crouch down low, and look through the grill) there is a separate "vane" which vents into the engine bay. HTH. :smiley:
BTW, that carbon engine cover is superb - me wants one too (but I'll probably get over-ruled by SWMBO! :cry:)

....You've managed to explain it pretty well. My understanding is that it's a separate 'compartment' within the lower part of the stock air intake (which has lots of 'compartments'). In which case, the Carbonio doesn't have it and is one big smooth open 'compartment' vent.
I certainly haven't experienced any performance problems since fitting the Carbonio but am naturally interested to learn what the consequences over pressurisation of the stock airbox might be.

....It's purely eye-candy. The stock grey plastic centre strip was looking grotty and very difficult to clean and so provided the excuse I needed. :smiley:
