What do you have for heat shielding in your engine bay?
|
Right now, nothing but a cold air intake (I am still NA)
In the future, I intend to have:
A cold air turbo intake.
An excellent intercooler.
Turbo heat shields.
Polished inside and outside of intake manifold (reflect radiant heat on outside, avoid turbulence that transfers heat to air on inside).
No coolant flowing through the intake manifold (I will tie the turbo in to the heater circuit).
Insulating manifold gaskets, lower temperature thermostat (cooler engine = cooler engine bay).
I might do the blanket on the turbo too, but that increases turbo temperature.
Keeping IAT low is critical in running lean, as detonation requires a certain activation energy. Even more awesome is that cool charge air actually makes the air more dense and makes more power at the same AFR and boost.

I like Aux injection, with the exception of two points.
1) No-One can definately speak about the wear that the injection causes by washing the oil off the housings etc etc
2) I have yet to see one kit that is fail proof. I am not completely up to date with Howards setup, but I am with BDC's..... now... you're using this piggyback system to inject whatever, and if you look at the fuel maps, you're pulling fuel, and ALOT of it out as soon as the boost comes on hard. Now, if ANYTHING goes wrong with the aux injection, it seems to me that it would cost you and engine right then and there. I'd gladly rock an aux system if I could run it off the Motec and have a few failsafes.

I am not sure about aux injection (I don't what it is), But I intend to drill the front and rear plate for injector bungs at the ports. I don't like how far the secondary injectors are from the ports (uneven fuel distribution from going around the turns).
