WANTED: MAF Meter

Struggling 2 find 1 in uk. But luckily my gran is in USA for next couple of weeks and she has agreed 2 bring sum bits and bobs bk for me, Handy. should save me a bob or 2.
I looking at the 52mm from suzukird has a few good reviews on there site, any1 no anthing more about it?
Do u need 2 upgrade the fuel rail?

no you dont need to touch the fuel rail. Ive also been looking at the suzukird one, but ive never heard anything good said about them. What i really want is a stock TB thats been bored and modified. Suzitech sell these but i haven't contacted them yet on price as the price listed is an exchange price which is no good for me

suzukird are good ive had lots of bits off of them clutch fuel rail arp bolts underdrive pulley


steve

Wot size is the modified standard 1?

Doe's anybody out there no were to get 1 of those anodised blue Rzm fuel rails like for sale with an engine on Teamswift?

I cant find them anywere but i've just got 2 have 1!

if you bore the maf meter out 2 48.5mm wot size does the sensor hole need to be made plz?

steve

well that told me then

48.5mm

increase the small hole the same percentage as the big hole, thats the theory anyway
the only way you will get it spot-on is if you use a standalone ecu, but if your goin that far then you might aswell go for itb`s

i have a 55mm srd tb , i got it when they 1st opend, its just a std tb bored to 55 with a new brass butterfly

Does your 55mm throttle body have any i'll affects on lower RPM's.
So if i can find another throttle body at a scrappy with a larger butterfly i could technicaly bore mine out 2 that and just change the butterfly? seem's like a cheaper method, or maby a disaster waiting 2 happn perhaps?

what small hole? you just bore the main hole and dont touch the sensor hole, dont you?

i have never bored the sensor hole and they all worked fine

Hi,

So you are boring out TB. Will it not reduce air velocity inside to reduce low down torque?
Have you driven Swift with over size TB? I'm just curious.
I just want to know what you are trying to acheive. Bigger bore is for the top end power.
If you are in circuit/sprint, you will use it often but in street/road.... do you get much benefit?

I will rather save my money up and fit better camshafts!
Oh by the way, I'm building ITBs setup using BMW bike ITBs for turbo charged engine.
For my NA, I got quad carbs from R1 so it is smaller bore that what you boys are talking about.

Cheers
Atchi

im not sure who your asking atchi but obviously i have im all about the top end power was a good little upgrade only downside is throttle is on or off not ideal for city hence why i aint doing it on my daily


steve

ive just done the cam upgrade, this is just the next step, im only going to 49mm, if i was fitting the 60mm TB then id agree with you. In my opinion, the stock TB and MAF restrict the power, so im just derestricting it

If u alter or have different cams in, does this affect the way it hits the rev limiter?
Bigger or smaller pauses imbetween redline?

tbh all this larger bore t/b bollox is realy just bollox, only bother with it if your goin turbo and using the std intake
if you using n/a with a mild setup you wont see much of a gain so like atchi said put the cash towards a set of usable cams and chip they are the one thing that will transform a n/a engine
i got my t/b when i was young and stupid, buying everything i could see
if i started all over again knowing what i know now i wouldnt buy most of the crap i have done over the years
and probabally be richer for it

gary

on a different note
atchi
i will have the same as you, 10mm sounds fine
hopfully be welding it sunday morn, thats if the mrs dusnt moan, feb 14th
