bromy Posted January 11, 2003 Share Posted January 11, 2003 Chris, How good is the design of the sump/oil pick-up on the supra engine with regards to oil starvation through cornering/acceleration/braking forces on track days, i'm thinking about doing some track time in the summer, a seized ford CVH engine many years ago has been putting me off, although i have not heard of any problems. I will also be in contact in the spring time for one of your de-cats for the n/a.

Need4Speed Posted January 11, 2003 Share Posted January 11, 2003 No doubt Chris will reply, but I've had mine at Sliverstone GP and Goodwood and there is no oil surge problem. Quote Link to comment Share on other sites More sharing options...
Terminator Posted January 11, 2003 Share Posted January 11, 2003 I am sure Chris will give a much better technical answer but I think the N/a Shares the same double oil pan arrangement with the TT. You need not worry the MKIV is design to cope, with several internal baffles in the sump to prevent the pickup strainer running dry under extreme G- forces.

B3any Posted January 11, 2003 Share Posted January 11, 2003 Phew that was one of my worries as well, Used to happen in the mini all the time Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 11, 2003 Share Posted January 11, 2003 Well, i used to add about .75 of a litre extra oil above "FULL" and drove my MKIV TT very hard on track, and never had oil surge problems. I guess on road tyres they aren't a problem. Put some trick suspension and slicks on though and it's anyones guess. Road tyres = OK as far as i have found. I'd be more concerned re oil temperatures, an engine oil cooler, bypassing the oil to water heat exchanger fitted as stock, would cool the oil better, and give the water cooling system an easier time. Where to fit a decent sized oil cooler is a bit of a problem though, N/S aperture, mirror of I/C one springs to mind. Squarish cooler, maybe a 25 row one?

Steve W Posted January 12, 2003 Share Posted January 12, 2003 [ BROMY, the CVH engine is NOTORIOUS for oil feed problems ! they are the BULK of our income ! With THEM it's not the pick up 'design' that's the problem, it's lack of oil changes leading to blocked pick-up pipe......EVERY TIME ! ! My RS Escort (basically a 'squeezed' CVH 1.6) was ALWAYS serviced - WITH FLUSHES - every 6,000. When I took the Rocker Cover off to do the Cam-Belt, I was SHOCKED to see the amount oil 'sludge' laying on the head ! ! = very disheartening. It normally leads to a narrowing of the pick-up pipe, much like Arterial Blockage !? and is OK round town/low revs but when the oil is needed the most - RACING - it can't do it ] Fat-boring-S.

Now be truthful Steve. You mean you took the rocker off every 6000 miles to replace the lifters don't you mate. Noth'n to do with the belt at all.......

Steve W Posted January 12, 2003 Share Posted January 12, 2003 NAH, honest, never had to do cam' followers EVER ! I think the oil changes did THAT much, at least. BUT, yes, you're right we sell LOADSA cams, then lifters, then cams... (the tits always insist on changing one without the other...derrr) {mind you I always had the stereo up loud } {and THAT WAS a UK car....nerrrrrr} Quote Link to comment Share on other sites More sharing options...

Steve W Posted January 12, 2003 Share Posted January 12, 2003 NAH, couldn't handle a 220hp RWD monster....... so, I BOUGHT A SOOP INSTEAD ? ? ? ? [ seriously, wanted something at least as 'quick' as RS but longer legs for motorway and AUTO'.... the Soop's not quite as quick round town - bit heavy and long and SERIOUSLY wrong for the wet ! ! = FWD rules IMO, I never even came close to spinning the RS, and that was stage 2 ! BUT, once on an open road....... ahhhh, bliss ] besides, I used to have a Capri 3.0 auto, and the Soop IS the Capri re-incarnated !....a PROPER coupe.

Matt C Posted January 12, 2003 Share Posted January 12, 2003 Originally posted by Steve W SORRY BROMY - shouldn't be nickin' your thread mate. Yeah Steve, dreadful doing that! I had a Cossie, liked it....good fun, NOT reliable though which is what I needed as an everyday car. I'd had MR2T's and fancied something different. I'd always liked the Supra but couldn't insure it til last year. As soon as I could....I bought one, then sold it......and then bought another!

No problem, all seems safe for the track, nothing for me to worry about. ____________________________________________ nick Quote Link to comment Share on other sites More sharing options...

I get enough money my intention is to, as you say, run an oil cooler in the NSF vent, nice large FMIC, and, to take an idea you suggested a while back, fit an auto radiator and run the PAS through the extra cooler at the bottom of the rad. Diff oil isn't a problem AFAICS as I have a (recently replaced) diff cooler as stock. One question I did have though was what about the gearbox oil - run that to the OSF vent once the stock SMIC is removed? Quote Link to comment Share on other sites More sharing options...

Have a look what gearbox cooling is already provided, but if it's inadequate you could do that, yes. Or LH rear wheel arch, probably enough weight forward of front wheel centreline as it is :-) Quote Link to comment Share on other sites More sharing options...
