wow it does work!!!

[V8FROG]

i changed my trumpets to ACT carbon and am pretty happy by how the car feels now.thank u TIM u are the man.
what shall i do next???
DAZ any idea???

Heat insulator and plenum spacer from SC Power!

Spoke to Tim about this, and he said this was the best combination for 'SIMPLE' improvement on the running of the car.

Link below will fill you in on the details

V8Frog, a couple of questions if I may... What size engine do you have there ? I see you have a smooth bore AFM-plenum hose, do you have smooth bore all the way to filter ? Also, I have exchanged emails with Tim and am looking to put the CF trumpets on my 500 in the near future, can you tell me what this mod has done to the car ? (driveability/smmothness/shunting wise)Many thanks mate,
Richard.

hi i dont have the smooth bore all the way yet!!well on my car i noticed a better torque midrange.4k rpm she really goes.shunting i cant tell as my car was always pretty smooth.hope it ll helps u.shame is too bad have to hide them under the plenium ahahah

tks for the link.the last time i talked to him he didn't answer my questions.trumpets are carbon fiber so do u still need to use the heat insulator.the are already shorter so do u really need the spacer???

Cheers mate, they do look good, thanks for the info Maybe a glass (pyrex ?) plenum top cover to keep them visible ?

You could of spent your money on

72mm plenun
46 mm trumpet base with short aluminuim trumpets
Port matched inlet manifold
£12.50 TVR POWER insulator gasket

Think around £450 seems alot for your money.

Would be interesting to see the results on a 4l or 4.5l.

The greater the space between the top of the trumpets and the underside of the plenum the better.

Unfortunately you would have to put a hole in the bonnet to get the ideal.

Take care.. what you gain in BHP can come off the bottom in torque... When I fitted mine I noticed the torque drop off a bit.... But that said, how does Powers blended base work??

[V8FROG]

yes no cats and center boxe replaced by 2 bullets and custom Y piece.everyone is telling me about the 71mm plenium.how much is it and what do u gain???

For the 4.0L and most 4.5l cars we prefer to sell the superflares, as the head ports are standard, if you go to the trouble of fitting a manifold that has been ported to match 45mm trumpets the gains over superflares are only about 5bhp & probably slightly less torque the cost is 50% more and takes 3 hrs to fit not to mention sending the parts for exchange, the larger plenum on a 4.0L will make no difference to power output.
However if you are say fitting ported stage 3 valve heads a ported inlet manifold & 45mm trumpets would be a good idea.
5.0L cars have a ported manifold as standard although 44mm at the trumpet end.
the 71mm plenum does help on the 5.0L engines, gains are about 3-5bhp.

There isn't a single formula suitable for all engines, if there was our life would be easy.

It is easy Tim! everything is different so each & everyone is right whilst simultaneously being wrong

Good point well made

[V8FROG]

alright TIM tks for ur reply.i am pretty happy with how the car behave now.and after fitting SH drop links it handles way better.my next mod will be i think the camshaft and maybe the head.as i am keeping this engine for the time been.

Glad you are happy, the head upgrade will certainly give you a good benefit, but think carefully about the costs involved, with standard pistons you can't go to wild on the cam and realistically will see a max of about 250bhp/ lb ft, email me if you want more info
