Yep, but you also need 312 carriers and 6mm worth of washers to move them inboard. The 312s are OK, but you'll be wanting some proper brakes if you ever go forced induction, such as TAROX, Brembos or AP Racing.

Saw the Blue MK2 close up, but didn't see yours in detail, but I heard it! I need to sort a 3" V band downpipe for a Corrado. Any where in the Ipswich/Colchester/Bury area that might be able to do this?

Evos are just overhyped. I've seen well driven 205 GTIs make cocky Evo drivers look silly on B roads! Everyone just assumes the Evo is ballistic and as usual, they form that opinion without actually driving one. They're heavy, brittle, thirsty, ugly and they're not even that quick either. I never said any VW can beat an Evo. Just so happened I took one out on a roundabout without much effort, doesn't mean everyone can though. I have a quaife, AP racing brakes, proper racing top mounts and expensive coilovers....so if anything, I had an unfair advantage on the Evo, LOL!

Whether Tom is/was Designadubs or not - I can't fault his advice and service at all!! I saw a couple of VR turbos he helped create at a recent meet in Bury St Edmunds and I was so impressed, I junked the charger and bought one of his manifolds straight away.....and now I have $5000 (£2600ish) worth of parts making their way over from Schimmel in the US of A. Can't wait for that 'whaba whaba whaba' idle more than anything else, LOL!

I've done an FQ320 with my 12psi Vortech setup. His was flaming out of the exhaust and making all kinds of racket from the over size exhaust, but I just floored it round him on a two lane roundabout and left it. The Evo is a rapid A to B car but it's also quite a big car, so not as agile or easy to place on the twisties as a smaller car....and the lag is terrible :-) You can't expect to get those kinds of outputs from a 2.0 4 pot without lag!
-
ibiVR initially, then Stealth for fine tuning if need be! I'll see how it goes. Should get all the kit by Wednesday and I'm sure I'll end up spreading it all out over the living room floor like I did with Lego when I was 5 :-) Can't wait!

VF's 10 psi pulley is actually 12psi, or 2.4". Get it from Raj at NSRacing. Got mine nice and quick, no probs.
-
You will also need a stronger gearset if gunning for the kind of torque that necessitates unbreakable shafts. Shame the Stealth/Gemini 6 cog set is no longer made. But there's quaife's set which can take the torque - at the expensive of service life.

Some good links on this site for the old squirt - http://megasquirt.co.uk/

Schimmel do them - http://www.spturbo.com/OnlineStore/DriveTrain/Axles/VR6Stage2System/VR6Stage2System.html

You got a schimmel aswell then? Great mod.... naturally aspirated too!
-
Exactly, otherwise there wouldn't be a 5V limit for the MAF signal....which that and stalling due to turbulence on the MAF are the only reasons we junk it. Of course we'd like to keep them, but tell that to VFEngineering who developed the kits.
-
Aye, you should see Bills 911!! $80,000.... but only £700 of that is the chargecooler....and he uses the exact same one on the 600whp car ;-) The reason chargecoolers can be ineffective are:- Poor core design Siting the core to close to the engine Insufficient water tank size Insufficient prerad size Insufficient pump flow rate Get those right and it's a sound cooling method.
-
If you pull the MAF, the ECU goes very lean, so balances out the red tops with standard chip. I drove 180 miles to stealth like that and it was fine. -
I've done ALL VR6 scenarios except turbo, but that's now in progress. I can say without a shadow of a doubt the Diff and 3.68 is better money spent than the schrick. You really need to experience that quaife doing it's magic to fully understand it's appeal. It gives astonishing cornering grip. The 3.68 does not affect motorway cruising in the slightest. All it does it put 5th in a more useable rev range. The engine is no noisier and economy suffers to the tune of 2 or 3 mpg tops on a long cruise. Don't get me wrong, I like the VGI but I got bored of it after a week and the dip in power at

Not a good idea as it's metered air being dumped off, the ECU won't be too happy. If you're not running a MAF, then by all means an at atmospheric DV is fine.
-
Higher pressure = finer spray but will need a remap to suit as to not swamp the engine. Aswell as a 4 bar regulator, corrados also got a 4 bar pump. There's nothing wrong with increasing pressure so long as you know what you're doing. It's a crude way of fuelling, but schimmel has run up to 20 psi with VR6 turbos with stock ECU, injectors and MAF and a high pressure pump / rising rate regulator, so it is possible to improve performance 'off chip', but it's not the best way. If Normally aspirated, don't fix what isn't broken.
-
My Corrado with 3.68 diff and quaife, schrick and 268s used to easily beat Civic TRs. 3.68 is the way to go. Makes better use of the engine's torque in the midrange, so no need to drop to 4th at 70. 5th will do just fine.
-
Schimmel's chargecooler is the feckin nuts. Speak to him and find out why. I've ordered one and a ATP GT30R turbo (GT30 turbine/GT37 compressor). His cooler setup supports up to 700hp and has virtually no boost drop. I've seen 4psi drops across small air-air ICs, they're ineffecient. The world's first 9 second FWD VW did not have air-air intercooling. It had the same Schimmel charge cooler I've ordered! :-) Let's face it, Schimmel is one of the world's foremost authorities on 12V forced induction, producing 680WHP 12Vs with is eyes closed, so what ever he uses, I'm bloody using!!!! Agree

Junking the MAF loses you a lot of the map, especially in the part throttle fine metering, so you lose throttle response. Tom is right in saying you need larger injectors and a larger MAF, but bigger MAFs aren't the easiest of things to map for smooth part throttle response. We tried a MAP sensor on OBD2 in my car, but a 2 bar one didn't work. Went into full throttle map too quickly. We think a 1 bar N/A map sensor might work but the one Vince had was duff, so we couldn't tell....but running mafless and a safe map is a good way to get round some issues for some people, but it's not ideal!

Just to support what Tom is saying (IbiVR) about costings, you can do it for reasonable money. This lot has cost me around £3,000 inclusive:- - Manifold and Spacer from Tom - Garrett/ATP GT30R ball bearing turbo + water and oil line fixtures and fittings - TIAL 38mm wastegate - Complete Schimmel Air/Water intercooler system - 15lb Braille Battery and clamp (has to go in the boot, so thought I'd lose a lot of weight in the process) - ARP head bolts - ARP rod bolts - BEGI dual adjustable fuel riser - 440cc injectors - 4" MAF - LC-1 Wide band controller and sensor Apart from the manifold and spa

Electric supercharging is the right step forward imo, but to generate enough boost, they'd need VERY powerful motors, so the alternator drain would be immense, almost like having a mechanical supercharger there in the first place, LOL! Until light, ultra efficient motors come down to mainstream prices, it's not going to happen. Why not just run a Vortech and a turbo? How come you've got lag? What turbo are you using?
-
Bets cc injectors for 8psi pully charged? also where from?
FishWick replied to 6potmkII's topic in Engine Tuning
138K it's on now. Head and chains were done at 93K and just a normal OE Victor Reinz Head gasket used. Charger went on at around 110K, so it's been reliable....touch wood. Tough old engines the VR! -
Was looking at that to help get the most from my Supercharger, but none of the ones I looked at (DTA P8Pro, Emerald, Lumenition, Etc etc) supported PWM steppered throttles, Idle filling valves and some don't even have sequential injection. Granted Sequential is not needed on a race track - where these standalones are born from - but it would be nice to replicate the standard ECU's smoothness and road manners where possible. One Standalone that is said to be the dogs gnads is MegaSquirt. It can do PWM throttle/ISV, Wide band lambda, sequential, Self learning, cam and crank triggers, MAP sens

Manifold looks excellent. Wish I'd know that a year ago! You have PM.
