AJA_GTi 0 Posted October 20, 2004 Report Share Posted October 20, 2004 Hello im new. &| My mates recently aquired '94 vr6 with 140k on clock and no history with a Jetex cat back and Ashley manifold with a none-descript cone filter. What general power increase would these modifications add and is the ashley any good?Cheers in advance Link to post Share on other sites
acf8181 0 Posted October 20, 2004 Report Share Posted October 20, 2004 very very little if anything. in fact, having an 'open' cone filter may well loose a few bhp cause it'll drag in hot air form the engine bay (and vr6's get very hot).at that mileage i'd wanna check the timing chain runners aren't comning apart (presuming it hasn't been done already) Link to post Share on other sites
antera309 3 Posted October 20, 2004 Report Share Posted October 20, 2004 The stock exhaust on a VR6 is unrestrictive right up to 250BHP, so performance exhausts don't increase power by much (1-2BHP at most) on a standard or mildly-tuned car.The only cone filters that yield decent gains on the VR6 are the ones with a heat shield & cold air feed, like the PiperX Viper or BMC CDA.

rudedubber 0 Posted October 20, 2004 Report Share Posted October 20, 2004 The stock exhaust on a VR6 is unrestrictive right up to 250BHP' date=' quote']this was posted on my thread ? i would have thought most stock exhaust to be fairly restrictive, even tho they might not add much performance surely a performance exhaust will add something ? (i could be wrong tho )>>>>>>When talking to Nik Saran, he said that the VR6 exhaust is unbelievably restricting, so less is more! However, you will lose torque with having a straight through one box system Link to post Share on other sites
Eat this 2 Posted October 20, 2004 Report Share Posted October 20, 2004 it certainly sounds good Link to post Share on other sites

andy 0 Posted October 20, 2004 Report Share Posted October 20, 2004 do ramair do a heat shielded filter then? I got rid of my ramair cone filter because it was dragging all the under bonnet heat in, ran better with the factory air box imo Link to post Share on other sites

six appeal 53 Posted October 20, 2004 Report Share Posted October 20, 2004 Yep, you only need to look at the RR results to see this! Its an age old arguement and to be honest I think they are all much for muchness.I think there's bugger all difference if I'm honest, although I love my Ram Air, lol!

Nerih 0 Posted October 20, 2004 Report Share Posted October 20, 2004 well its a fact that cold air is better for your engine, so if your induction kit doesnt have access to it, it really doesnt matter what you have... Link to post Share on other sites
binliner 0 Posted October 20, 2004 Report Share Posted October 20, 2004 tom had the same problem with his ram air didnt he?Back to the original question Id say if you really want to know what the power is get it on a rolling road because all we can do is guess Link to post Share on other sites
Geastb 0 Posted October 21, 2004 Report Share Posted October 21, 2004 I've got andy's ram air on mine - i'll be interested to see what output i'm getting next sunday! (I ain't got a cold air feed yet so best sort that out too!) Link to post Share on other sites

Eat this 2 Posted October 21, 2004 Report Share Posted October 21, 2004 hm thats a mixed bag Link to post Share on other sites
andy 0 Posted October 21, 2004 Report Share Posted October 21, 2004 I found the ramair fine out on the open road when you're getting loads of air to it, I changed jobs and started sitting in traffic a lot and the car just wasn't happy, melted two idle valve sound deadners which caused all manner of running problems (until I removed them ;-) ) its a viscous circle too, hot air in the inlet makes the car run hotter, hotter under bonnet temperature, even hotter intake air.... Not sure the VR is the best car for an unshielded cone tbh. Link to post Share on other sites
andy 0 Posted October 21, 2004 Report Share Posted October 21, 2004 RR days don't always tell you how the car will be on the road either, people quite often run on the rollers with bonnet open and a gert big fan in front of the car, not really representative or normal running conditions. A cone filter will always do very well when there's enough cool air about Link to post Share on other sites
VR6Pete 1,455 Posted October 21, 2004 Report Share Posted October 21, 2004 but when all cars are ran in the same manner, it's a valid comparason. Link to post Share on other sites
binliner 0 Posted October 21, 2004 Report Share Posted October 21, 2004 true Pete but Andys got a good point... you might see a few extra bhp on the rr from a cone filter but when you're on the road and the engines hot you might not actually be gaining anything from it at all Link to post Share on other sites
Slim 0 Posted October 22, 2004 Report Share Posted October 22, 2004 Is there anywhere that sells/fabricates shields for VR6 engines with cone filters? Link to post Share on other sites
