good enough!

[Pedro Fandango]

between the F1 & the rain i managed to get the grinder out again. Didn't take 5 minutes to do the bottom IC to throttle body pipe, just got to get a 20mm T-piece welded on for the idle control valve then the turbo to IC top pipe to do

2 questions if you dont mind

1. what did you do about the pipe that goes to the IAC?

2. the piping that you've got, it's narrower where it needs to fit and then looks maybe 3" the rest of the way. is it not a case of only being as good as the narrowest bit as far as flows concerned? am not trying to imply anything, just genuinely curious.

the what lol? If the IAC is the idle control valve (which is the only pipe i've got coming off that one) then i've got to get a 20mm pipe welded into the stainless section. I did toil with the idea of having the idle valve get its air straight from the engine bay, i tried this but the engine wouldn't fire up. But i think the problem was that the MAF sensor isn't sending a signal to the ECU as no air is passing, i think giving the MAF-ECU wire a 1volt would solve that but can't be bothered to try it yet (i can always remove the T-piece at later date)

your right & i totally agree you could well be right, but if replacing the throttle body with the larger 960 one while you've still got the orignal 50mm pipes for the rest of the system makes a difference then i've got my fingers crossed (it hasn't cost much & looks nice if nothing else lol)

thanks for that, understood up to this point.

dunno about the 960 one as i have an enlarged standard one. at one point it was the only mod done and the difference was very noticeable. not so much in power but in response between 2 and 3k

pleased to hear it

on idle the MAF gives the ECU 1volt saying "i'm happy, we're sucking in air", but with the IAC pipe bypassed its not. So with the help of resistors give the ECU the 1volt wrapped in sunglasses & a false mistauche so it doesn't know any better (just me working around the ECU again lol)

its exactly the same principal, Tim increased your throttle body from the standard 55mm to ?mm & you've still got 51mm connection on the bottom of your IC. I am worried that because the pipes will take more air to fill it will result in more lag (only time will tell)

you thinking of making new pipes up for yours?

thanks for the info, as for me, long term aim is to replace my intercooler or at the very least help it. three options at the moment are water injection, replacement intercooler or a tradional jap type FMIC.

having the bumper off this weekend hopefully so should be able to see how much room there is for myself

[Tim Williams]

Pedro if you try and run with the IAC drawing air from the engine bay then you will have a little boost leak, well no boost to be precise

no problem mate. Just please me carefull if/when listening to anything i say lol, i like to do things different & prepared to be a border line to do that (ie no air filter) & wouldn't want people coming back to me because its done their car any damage because i was prepared to do it on BT

go with option 1 & 2 (ditch the FMIC ), good luck with it & any chance you can PM/email me some pics with the bumper off

ah there you go T-piece it is then, thanks alot Tim

Hi Ped, now tell me is not the F1 championship without a doubt biased to Ferrari after to-days result? Running without an air filter then junk the mesh as well as it will fook up the air flow, either way you will need an engine re-build in 12 months mate if you drive it a resonable mileage, been there done it, makes loads of power but

[Callyuk]

you took the other pipe off the pedro or are you doing work on it?

i was in denial that the race had ever took place after Kimi ended up in the wall & only just looked up any news so first of seen of that, boy is it lovely to see that story (no your right, he doesn't deserve to have it taken off him, he did let him back past)

i did get a PM from a man in the know saying the same, might look into an Apexi cone & just use the straight thru pipe for the1/4mile then

Hi mate. i've still got the MAF sensor to mount into the intake pipe so its not ready to be used yet

I have a feeling it might get reversed as apart from Ferrari die hards nobody can see the logic of the stewards decision, but then again I also thought it would stop raining this year

i have to disagree, if the stewards are stupid enough to punish him even tho he gave the position back there stupid enough to stand by it (am i actually defending Hamilton here)

being a very knowledgable man (& trying to keep it on topic lol) i'm interested in your opinion to whether using 3" pipes will have any advantages or disadvantages (ie lag)

Sounds like it mate, will wonders never cease its now going to the FIA's International Court of Appeal so watch this space as the Italian GP is this Sunday
........as regards your intake it really depends a lot on other factors as you probably know, so matching your compressor wheel to the intake is a must as this creates much of the air velocity, hence the turbine and exhaust side also come into play with regard to lag and boost threshold. It's worth bearing in mind Ped that the total air mass never changes only its density, pressure, temp and velocity, so let your turbo do the business, only then will we see at what RPM the power band kicks in, having said all that b------s,
