matt_corradovr6 0 Posted January 22, 2007 Up at santa pod at the weekend and could not get quicker than 15.9 with terminal speed of 91 mph. bit gay. thinking bout gettin manifold and de cat pipe and cams. heard that the 6 branch won't give any more power, and then heard that it will. what do you reckon??

steve @ 0 Posted January 23, 2007 May give a little more but not much. Fair bit lighter though. The VR's gearing is not suited to the 1/4 mile. 3.68 final drive will help. Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted January 23, 2007 Agreed. Gearing is one way to improve times. A well designed and lagged 6 branch can show improvements in midrange torque though and VRs seem to respond well to decatting also. Quote Share this post Link to post Share on other sites
matt_corradovr6 0 Posted January 23, 2007 My mate has a similar spec to mine but de cat and heat shield around induction, producing a little over 200 horses and the bugger got 14.7 Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted January 24, 2007 Maybe he got a better launch? :-) I hate to say but a lot of 1/4 mile success is down to a good launch.... Quote Share this post Link to post Share on other sites
matt_corradovr6 0 Posted January 24, 2007 maybe. gonna do some tuning and then get back on there. Quote Share this post Link to post Share on other sites
eatthis 0 Posted January 24, 2007 its all down to the first 60 ft mate 2.1 is the time your aiming for i got a 14.6 in my golf Quote Share this post Link to post Share on other sites
matt_corradovr6 0 Posted January 25, 2007 Quality eatthis! think i'm just gonna try and tune when funds allow. think that cams are first as head gask needs replacing at some point soon, then decat and manifold and need to sort a better cold air feed to the filter, but i'm not sure where best to locathe the tubing to the filter?? also my cam pos sensor is randomly faulty. vince said it will feel like losing 30 bhp, so i'm gonna blame that for the poddage runs!!!???!!!

RADO.001 0 Posted January 25, 2007 sorry for the hi-jack but is it worth fittin 268's with the standard manifold? Quote Share this post Link to post Share on other sites
bananawhip 0 Posted January 26, 2007 Sorry to jump on this but mine is vagely related so here goes... My bro' is scrapping his 1989 mk2 G 16v and he has a custom 4 branch exhaust manifold, I'm sure he bolted it straight in to his original system so whats the chance of it fitting mine and is it worth it?? As you can see from my sig I've got a 1990 valver, To my delight it's 0-60 time is down from a standard 8.9 to a self timed but consistant 7.5 all from the following mods.. 50mm inlet Drilled airbox (boy racer I know but sounds funky) Miltek full system Ecotek valve k&n panel For that time I reckon it's gotta have around 150bhp which is impressive given 117k on the clock. So boys and girls...Shall I bother chucking it on or not? Quote Share this post Link to post Share on other sites
Deluk 0 Posted January 26, 2007 sure , but leave the ecotek valve WTF? Quote Share this post Link to post Share on other sites
bananawhip 0 Posted January 26, 2007 To be honest apart from the stupid noise it makes when returning to idle it has made a fair bit of difference. Just makes the car feel a touch newer and smoother, little more eager and pull's a fraction harder. Haven't seen any great fuel savings yet though. I'd genuinely recommend them and for £35 good as new with the piper-x filter from ebay it would've been rude not to. Quote Share this post Link to post Share on other sites
matth76 0 Posted January 27, 2007 sorry for the hi-jack but is it worth fittin 268's with the standard manifold? Yes you can fit 268's with standard manifold. I have a stainless 6 branch fitted to my golf vr6 and it made virtually no power increase whatsoever - I had a before and after rolling road session. No bhp increase at all, if anything a few more lbs/ft torque. Then I started developing a small blow less than 6 months later (and I have uprated engine mounts proper flexi joints the lot still made no difference and mine is a good quality one supposedly). Not worth the hassle in my eyes mate. Spend your money on more efficient mods - definitely go for a decat or high flow cat and get the cams, full exhaust and air filter. My 268 cams gave a good increase - about 10-15bhp. You must get a custom remap though after fitting the cams otherwise you will say goodbye to your engine. The remap is vital to get the altered fuelling spot on. I got some second hand Eurospec cams - which use the same profile as Shrick cams. I was told not to go for any other make as you will lose low down power - whereas with Eurospec and Shrick cams you lose hardly any low down power at all. I have also heard a slightly different "final drive" ratio gear cog can be fitted but was told this was very expensive and advised my local vr6 specialist not to go for it - I mean you're looking at £1k-£2k as you need to get a quaif or peloquin diff fitted at same time.

eatthis 0 Posted January 28, 2007 sorry for the hi-jack but is it worth fittin 268's with the standard manifold? yes when a added a 6 branch with 268 cams and got it remapped i gained 25 bhp at the wheels and 30 lb ft at the wheels! my figures went up to 178 bhp and 175 lb ft at the wheels Quote Share this post Link to post Share on other sites
CorradoVR6-Turbo 0 Posted January 28, 2007 Fitting one item at a time will see little to no BHP increase at all but do them with other mods you will see a difference. Any help to make the VR go faster cheaply is going to be tough! Quote Share this post Link to post Share on other sites
bananawhip 0 Posted February 12, 2007 Sorry to open this one back up but I'm still none the wiser if a mk2 16v has the same exhaust manifold/downpipe as my little yellow bundle of love. Any idea's? Also whist I'm on here is there much difference in performance between the 2.0ltr and the 1.8 valvers? I kinda fancied something a little newer then mine but quicker and still with alright mpg and insurance. Quote Share this post Link to post Share on other sites
