Kevin Bacon 5 Posted August 11, 2010 I haven't seen throttles on turbo inlets before, very novel 8) As a guess, it looks like they pushed for maximum flow. With no throttles on the head and the turbo throttle wide open, you get a completely unimpeded flow path into the cylinders. It's a simple and clever idea :notworthy: I imagine Anti-lag would work better aswell. I don't think it would work particularly well on a road car as the 'throttle response' could prove tricky to manage at slow speeds, i.e. going from idle to half bar boost over a very small throttle opening!! F1 engines usually idle at 4000ish rpm and rev past 15K. Whereas we spend most of our time at idle to 3000rpm :lol: Quote Share this post Link to post Share on other sites
VR6Joni 0 Posted August 11, 2010 Read a few opinions on this, it seem very good for anti lag, negates requirement for BOV. The turbo can spool up quicker due to the greater differential pressure across the compressor and less work to do as the air mass is much lower until WOT. However there are also numerous disadvantages, solid boost pipework needs to be used and a leak can end up in WOT! Turbo life is often reduced due to higher shaft speeds to compensate for running in a partial vacuum and the oil seals tend to fail earlier due to the vacuum present in the turbo.

Kevin Bacon 5 Posted August 12, 2010 Cool stuff! Yeah I read a bit of that thread afterwards and one guy likened it to putting your hand over a vaccum cleaner hose to build up that pressure differential you mentioned. I struggled to picture in my head how it would work, but I guess it must! Loving the glowing turbo manifold too... an ideal place for the neighbour's cats to fall asleep :wink: :lol: Quote Share this post Link to post Share on other sites
Philmo 0 Posted August 12, 2010 Some gallery that! Where's the turbo museum? New F1 formula certainly something to look forward to. Do IRC that it was BMW who held the title for highest specific bhp from an F1 engine? Quote Share this post Link to post Share on other sites
coullstar 0 Posted August 16, 2010 Gents, are we definitely on for the 19th Sept then for the RR day? Im looking at options for the Sunday day / night. If it is worth putting up a post in events section. If it not on then I can just travel down on the Sunday as the cars getting the Racelogic fitted on the Monday.

coullstar 0 Posted August 17, 2010 Quick question on this. How do they secure the cars when on the RR as I dont have the rear towing eye? Quote Share this post Link to post Share on other sites
CorradoVR6-Turbo 0 Posted August 17, 2010 front tow eye and on the rear of subframe or jacking point holes in floor up front. Quote Share this post Link to post Share on other sites

Kevin Bacon 5 Posted August 20, 2010 Yep, Vince has confirmed the 19th is a goer :D I will call him nearer the time to find out what time he wants us there and any other minor details.

pete_griff 0 Posted August 20, 2010 don't think i'm going to be able to make this :( :( :( as it stands i'm set to fly out of the country on the 17th and somehow i don't think getting a later plane is an option for me! obviouly i'll keep you posted an if i can make it then i will... anyone want to take the M5 along for me?!? :lol: Quote Share this post Link to post Share on other sites

muppetlab 0 Posted August 24, 2010 I am looking at supercharging my Vr at the moment but the thing that stopped me was during the recent rain storms i thought about where the filter might be. Turns out its right down the front near the wheel with the vf vortech kit. I dont have arch liners due to wheel coilover set up and am very concerned that the filter is doing to get a good drowning if i drive through more than a small puddle. Do people have problems with this, is there a solution? Does anyone have any pics of the filter in situ, i guess its pretty much where the charcoal filter is from what i have been told. Thanks for any replies. I will search this thread but its a bit of a monster to get through. Quote Share this post Link to post Share on other sites
buttles 0 Posted August 25, 2010 The Air filter will get a good soaking on a wet road let alone a puddle without arch liners. There is not enough room under the Cannister hole to put a filter protector on so the filter is open to the elements. I never had a problem with the position of the filter with the liners in place. If you do go down the VF route give me a call, got one sitting on the shelf! Neil Quote Share this post Link to post Share on other sites
muppetlab 0 Posted August 25, 2010 Hmmm so no liners equals wet filter, not good. Will have to look into other solutions. Quote Share this post Link to post Share on other sites
