Alex Posted August 18, 2005 Share Posted August 18, 2005 Those that have done it before. Can you tell me what you used? Circular cutter? Drilled a start point a used tin snips from there? (don't know how thick it is) Angle grinder? Hacksaw? I'd like a fairly neat circle but I think I want it bigger than any circular cutter I own...or should I just do multiple smaller holes?

Matt Harwood Posted August 18, 2005 Share Posted August 18, 2005 I bought a 6 1/2" hole saw. They're not cheap though. I think it was about £40 ish. You also need a good drill. The surface is uneven and a lot of battery drills get snagged up as Dude found out You also need to be careful as some wiring is clipped up just underneath the panel you'll be cutting into.

Alex Posted August 18, 2005 Author Share Posted August 18, 2005 glad you told me about the wiring...though I'm sure I would have checked first...well you'd hope I would I think a 4" hole saw will see me right...I'll check Machinemart. thanks Link to comment Share on other sites More sharing options...
terawua Posted August 18, 2005 Share Posted August 18, 2005 Alex... dont use Machinemart.... they're very expensive.... use ITS (Industrial Tool Supply) in Leyton, London, they do a hooge hole saw 170mm or something like that for about 25 quid if I remember correctly - a veritable bargain. I have been planning to do just this (I am assuming a cold air intake, yes?) on my car but havent got round to buying or doing it yet. I would have posted you the hole saw ifI had it so you could borrow cheers James Link to comment Share on other sites More sharing options...

Alex Posted August 18, 2005 Author Share Posted August 18, 2005 Thanks James...yes indeed it's for cold air feed...as I have an FMIC I'm going to duct in some lovely cool air. Link to comment Share on other sites More sharing options...
terawua Posted August 18, 2005 Share Posted August 18, 2005 they are comparable in price to ITS.... so go for it if it is easier, just remember you need the arbor as well oh and I might rent it off you.... go for a big'un though... Link to comment Share on other sites More sharing options...
terawua Posted August 18, 2005 Share Posted August 18, 2005 Yes I need to do this too...... worth 10hp isnt it (so I heard!) Link to comment Share on other sites More sharing options...
Alex Posted August 18, 2005 Author Share Posted August 18, 2005 I was going for a 102mm BUT I'm not going to order it till I've found out what size of pipe I can mate upto it. Link to comment Share on other sites More sharing options...
terawua Posted August 18, 2005 Share Posted August 18, 2005 I was looking at pipe too.... are you going to get a 90 degree elbow to mate up to it? Link to comment Share on other sites More sharing options...
Alex Posted August 18, 2005 Author Share Posted August 18, 2005 I'm not sure if I'm going for solid pipe or a flexi pipe yet...it may well be that the parts used look (*read ARE*) like guttering bits. as that is big bore and comes in lots of helpful shapes....i'd like to get some sort of funnel covering the whole duct and ramming air up the pipe....but if I go too OTT I expect issue's with air pressure under the bonnet.

terawua Posted August 18, 2005 Share Posted August 18, 2005 Yeah I was looking at guttering parts. Also a nice ram air effect would be good... I was going to have the airbox sealed from the underhood air...... Link to comment Share on other sites More sharing options...
Terminator Posted August 18, 2005 Share Posted August 18, 2005 Alex, I have cut quite a few holes in various cars and have a range of saws. The last two we cut were on my sons conversion. I have found that steel lined plastic covered door or window edge seals from a breakers make a perfect wrap around cover for the edges of the holes. The spring "teeth" give excellent grip on the hole keeping the seal perfectly circular. The car is in the paint shop so I cant take a pic to illustrate what I mean.

peter richards Posted August 18, 2005 Share Posted August 18, 2005 i have hole saws of various sizes , it might be cheeper than buying your own , just pay the postage , and you can borrow them . if it helps Link to comment Share on other sites More sharing options...
Alex Posted August 19, 2005 Author Share Posted August 19, 2005 cheers Termi...I think I know what you mean but a pic to confirm would be handy...think you mean the rubber strip at the bottom of the window that stops rain getting inside the door? Peter, I may well drop you a PM...I'll measure up this weekend...I'm also debating relocating the filter to the SMIC position... Link to comment Share on other sites More sharing options...
RobSheffield Posted August 19, 2005 Share Posted August 19, 2005 i was going to do this with a Blitz SUS....drop it through the lower panel, but i was told that water damage could occur...now im not sure! it must be worth doing! Link to comment Share on other sites More sharing options...
Alex Posted August 19, 2005 Author Share Posted August 19, 2005 Whoa there...this is not me trying to extract more power but to fix my problem with my VVTi throttle... Ewen has found his was fixed by using the stock airbox. I don't have that luxury so I'm trying to cool my charge temperatures via other means. I am not going to say yeah do it to your car too...

penguin Posted August 19, 2005 Share Posted August 19, 2005 Alex, any chance of a few pics once your done? would be nice to see how you've located it.... my engine bay is a lil on the warm side at times! Link to comment Share on other sites More sharing options...

eyefi Posted August 19, 2005 Share Posted August 19, 2005 alex, i didn't bother cutting that panel at all, i just put a triangular scoop at the gap that is behind/underneath the light. this brings in plenty of ambient air. my filter is also sealed at the rear and sides and i have no indicators, which helps. intake temps are great. for anyone thinking of sticking the filter down through that panel and into the smic position i dont think that's a good idea, it's prone to water damage (paper filters), extra dust and it's a low pressure area.

terawua Posted August 19, 2005 Share Posted August 19, 2005 for anyone thinking of sticking the filter down through that panel and into the smic position i dont think that's a good idea, it's prone to water damage (paper filters), extra dust and it's a low pressure area. I think B'have has done this, but he has the luxury of owning two supras, and I think that he has done it to his trackday beast, so I bet it only sees nice weather!

Alex Posted August 19, 2005 Author Share Posted August 19, 2005 I've got a Whifbitz bumper that might not duct things as expected or give me the room to use the under light option... I need to jack the car up and give it a going over in this area....Heat shielding and investigation of ducting options will be tomorrow's tasks.
