i borrow u my dremel set + digital caliper la TR...u belanja me lunch + kopi o peng enuff

 

[TitanRev]

digital caliper I have arturo...don't have DREMEL tools....actually how much is the price for a set of DREMEL??

 

[arturo]

i got a quote of RM785 for a dremel 395 multipro + a flexishaft + 55pcs accessory back in june...but i'm using a dremel 300 multipro (rm300)...the model before this + a 400pcs accessory set from rs-online for rm88 hehehe

quite hard to find suppliers who have stock on hand...the quote i got had a back to back order...so i'm guessing he had to order from the states then only send over the dremel.

Eh.. to those who DIY this TB polish, make sure you don't get overzealous with the polishing otherwise if your butterfly plate is smaller than the TB outake mouth, you're gonna have big time idling issues.

Izso...vaccum leak from the tips of the butterfly valve?

Use hand ah ??

cos the main point is not to port it bigger, but smoother... just like how u done to ur throttle ma...

Yeap. My first TB I polish kilat kilat and I increased the throat size without considering the butterfly plate. When I face the TB against the sunlight, I can see a full sun eclipse one.. very the bad. Idling was crazy!

2nd TB the 'eclipse' was much smaller and lucky for me it didn't cause any idling issues.

TR taikor, after u did d porting a bit... did u feel any difference in acceleration?

 

[JINEIL2EN]

unker fred wanna feel his car..??

 

[TitanRev]

unker, acceleration did improved and the rev also goes up faster especially during the low range but still slower than your Gymkhana monster...

Izso, yeah..you are right...the butterfly valve area cannot touch....can only do the area before the BV and after the BV.

Arturo, wah quite expensive....

I think my hand will become cacat after that...

Eh taikor.. I tot you tukar to T3t3k besar (TB) besar already? Nothing beats a bigger TB but low end will be a bit hard to control so I'm told.

when you gonna to twin t3t3k besar?

 

[JINEIL2EN]

if just doing the front part, thats will lead the venturi effect, air will be compress & better air flow... nice...

 

[TitanRev]

I also want TTB...Hehehehe

 

[JINEIL2EN]

I think my hand will become cacat after that...

won't la bro.... slow slow do ma....

 

[Izso]

I also want TTB...Hehehehe

Without meaning to sound off topic - the twin TB setup has actually been done with really good results.
