The LZ9 MGB is finally running

[CNCguy]

It has been a while but I finally got to take the MG out. The tuning still needs work but is drivable. The 3.89:1 rear gear is too much with the small diameter tires and I want to change it at some point. A 3.23:1 or so would be a huge improvement. It is fairly easy to take off in 3rd gear.

i don't know if its the camera or my laptop speakers, but that doesn't sound like a 3900....

[CNCguy]

It does sound a little different doesn't it?

Edit: It's not your speakers... it sounds like pretty much like that.
Here's what it sounds like inside the car.

so what was done to it to sound like that? cam/exhaust?

[ForcedFirebird]

Awesome! Looks like a lot of fun to drive hehe.

[robertisaar]

yeah, looks fun but almost sounds ricey.... i don't get it. i've never heard another 660 sound like that.

[CNCguy]

The cam has 260/264 duration .562 lift & 110 LSA. The exhaust is BCC shorty headers into about 30" long 2" pipes that merge into a 2.5" cheapy turbo muffler with a 18" long straight tailpipe.

It is fun to drive. Punch the pedal at 1500 rpm in second gear and it breaks the tires loose. It's cool but the kind of car that can get me in trouble.

[robertisaar]

cam sounds nice and healthy..... i'm guessing it would be the cheapo muffler...

[1988GTU]

I dont get those cars, whyyyyyyyyyyyyyyy?

Guess if it floats your boat, cool.

[robertisaar]

lightweight, RWD, vert(or is it completely topless?)..... whats not to like?

[1988GTU]

It looks terrible... Look at the miata..... UGLY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! and a woman's car.

[IsaacHayes]

Put a H or X pipe and it should sound better.

So details, variable intake: functional or or not? If not maybe try the 3500VVT upper instead...

VVT? disabled and locked? Or gen3 cam setup?

Womans car is fine with me as I have no doubt about my manhood.

Womans car is fine with me as I have no doubt about my manhood.

even though thats a very good point, you'll never see me driving/riding anything pink..... or a miata......... hell is a pink miata: i finally understand the meaning of life.

[CNCguy]

I really am not too worried about the sound at this point. If anything I want it really quiet. No need to attract attention.

I am basically running a GEN-III cam setup and have not experimented with the variable intake yet. There is an LZ4 plenum sitting here to do some comparisons with.
