A Problematic Free-Flow !!! - Team-BHP

dustDevil · 28th June 2006, 22:12

I bought a free-flow for my Zen(carb) from auto-mech... there are a few problems that i am facing:
1. The exhaust-part that just follows the manifold is much lower than the stock one, reducing the clearance by almost an inch! it'll be the first thing to hit any obstacle getting under my car. will it break easily.... do you think i should get a new unit to replace this (though it'll be very cumbersome)?
2. It almost touches a body part (about 4-5mm from it) just below the gear lever. So whenever it vibrates, the vibrations are transmitted to the body.... will filling silicone gel in the gap solve my problem?
3. a part of the intake manifold touched the "cross"(well thats what the mechanics called it) that it passes through so i got abt 3mm of it cut, to enlarge the hole.... hope it wasn't a bad move!?
PLEASE HELP....

I Believe the problem is of installation,
I agree it reduces the clearance, but it must not by hitting road so often though on indian roads you can expect anything,
there are some ways out..
first is checking the installation from bottom , you got to check in garage where they have car lifts,
about Filling I think silicon gel may melt due to exhaust heat
that 3 mm is the not worry issue,
one jugaad i can suggest here to raise up ur car by adding 1"- 2" thick rubber to suspension..

Hi,
The problem is a misaligned installation. Get it reinstalled and your problems should be solved.

did you cut your cross member?

dustDevil · 29th June 2006, 10:07

No, nt exactly the cross-member....... cross-member is the part on which the steering rack n' pinion is bolted.... right!? The part i cut is in the front, just below the radiator. i'll post a pic soon...

Cross member is place where the engne rests.Engine is supported by engine mountings too.The part u said u cut below the radiator is the cross member.

I thought the handling goes for a toss if you do that!! Are you sure you could?? The best would be to reinstall the headers..

okay...... so u cud say, i enlarged the hole in the cross-member (through which the exhaust pipe passes) by about 3mm..... is it gonna have any adverse effects?

I'm still to give it a bit of finishing and apply paint to prevent rusting! should i use an epoxy paint or oil-paint should do?
