How much power with this setup?

[Aikio]

Hi..

I\'m upgrading my rex @ the moment, and was wondering how much power I can expect to get out of the engine with this setup:

Standard ports,
apexi twin intake
3" full straight through exhaust
RP Racing fuelpump
Secondary fuelrail kit with 1680cc injectors from KG parts
Greddy style front mount IC
Godspeed radiator
Apexi Power FC
Block off kit, removed double throttle control .
removed airpump
MSD 8,5mm spark plug wires.
BUR9EQP sparkplugs
ported wastegate.
1 bar boost
Innovate LM-1 wideband lamda

Thats all I can remember at the moment..
Anything else I should get???

Thanks.

you running standard twin tubs?

300 at the wheels

you running standard twin tubs?

Not sure what you mean with tubs??

He means are they the standard sequential twin turbo\'s, or are they upgraded i.e. 99-spec twins, or an aftermarket hybrid like knightsports. etc.

With regards to power, depending on how healthy the engine is and who does your mapping expect anything from 280 - 300 rwhp.

[Aikio]

Ahh... they\'re still sequential standard twins.
The engine was rebuildt about 15000 km ago... not sure what thats in miles 9500 or so..

[skybusr34]

agree with blitz, up near 300wheel horse power

300-320 WBHP dependent on dyno at 1 bar. As long as you can keep air temps low enough.

I can\'t afford a vented hood at the moment, but I\'m planning on doing the "drift" style thing where you move the back of the hood up a bit, so you get a gap between the back of the hood and the windscreen. hopefully this will let some of the hot air out of the engine bay...

Just sort of finished my dashboard and doors.. they are suede/alcantara thingy...




I\'m waiting for rotaryarts rotorshaped gaugeholder to finish it off...

mate that looks good! i have just finished doing my dash too!
 
by the way on the door cars have you cut out where then vent bit is, or is it all just coverd in one part! also whats with the red line?

[BlitzBoy]

groovy dash like it

[Aikio]

I had to cut it at the middle, along with the armrest/door opener handle thing, and down along the edge of where the door hits the dashboard.

The red line is there to cover up where it was cut, but it turned out a bit more cheezy than I\'d expected, so I\'m going to change it for some sort of black rubber stripe...

[Draco]

very nice dash indeed...

[ENVYD]

ahh ok mate! what glue did you use to stick it down with?

This doesn\'t really have that much effect.  You have a high pressure zone at the base of the windscreen.  This is, I agree, slightly less than a standard saloon due to the decreased rake of the windscreen but non the less it is still an extensive high pressure zone.
 
This Zone actually contributes towards down force.  Unfortunately it is counteracted by the lift generated by both the bonnet and the roof, but is why you see the faster sports cars with a very shallow long screen as this smooths the transition between the bonnet the windscreen and the roof.
 
As air moves from a high pressure zone to a low pressure zone, and the air under in the engine bay tends to be low pressure, the air wont actually come out very easily by the windscreen.  If anything it will want to circulate under the bonnet causing drag.
 
The best way to remove air from the engine bay is either via the bonnet using NACA ducts or under the car between the chassis and a flat floor then exit at the rear into the dead air.
