It's a flapper!!

[Waynester]

Just noticed something earlier.. My SEAC is a FLAPPER

It's the one thing i miss(ed) with my 400. Being a hot wire it didn't pop and bang.

This one does! Only little pops/bangs so far as i've only driven it 3 times, and then gently as i'm finishing the running regime.

Plan is to change the standard exhaust silencer for a more 'sporty' affair, then give her some beans. Should sound awesome then.

Pops and bangs on the over run make me grin as much as when i boot it.

Lucky b ...
It all adds to the 'presence'.

I really miss the pops and bangs from my 390 flapper.

Hmmmmm ACT Carbon plenum and stainless exhaust

Pricey, but worth it

Aye 450 on a flapper is the best

One of the reasons I've still not changed my ecu system over as I will miss the noise

Wayne - that's excellent..

Something my SEAC missed was the pops and bangs as it's a hot wire.

Mind you - now I have an Emerald - I can have a pops and bangs map on one of the map switch positions one of the other guys with an Emerald did a pops and bangs map and said it was like having a gatteling gun

Agreed, look forward to hearing that Alan.

Flappers are awesome arent they! The pops and bangs from ours is unbelieveable, ask Blaine or Gandalf!

The 450 has some serious grunt, and we've found out that our engine is rather special with Cosworth Pistons!!

I thought all the 400SE's and above had cosworth pistons, I know mine does. 1989 400SE flapper.

That's what i thought too, NCK engines...Cossie pistons, or am i getting confused with just SEAC's?

[grahamw48]

In another thread it was mentioned that only the 390SEs (and SEACs) had the Cossie pistons,
and later engines were a little less sophisticated...hope not.

Mine has a 1995 hotwire Chim pre-serp, so heavens knows what it's got.
I think my flapper 390 was quicker though, but heavier on juice and oil.

Don't remeber my 400 having cossie pistons either ,pretty sure they said omega or something.

Not checked the 450 (Ex 1992 Chim BV)

[jagdpanther]

Fairly certain SE's and SEACs both had Cossie pistons

Nope, not many left TVR Power with Cossie pistons, only the odd few (Thats what i was told anyhoo. By someone in the know too!)

My '7's got cossie pistons ( HPC vaux ) . Hope the seac has too !

None of the Chim 4.0 had cosworth piston, IFAIK, the engines came from LR, and just had a camshaft change and different ECU chip.

by this time the 4.0 was at the bottom of the range, where as the SE/SEAC was at the top at there time.

my 400SE also had ported heads. and double valve springs.

I think the 350SE used the chim engine/method
