why such a big gain in BHP????

[clio head]

Sounds stupid and i can kinda think why....but why u get such a increase in BHP wen u install a Throttel Body?

huh?

 

[Andy GDI]

you mean throttle bodies??

if so, because you essentially get so much extra air into the engine

 

[clio head]

I think I saw a set up on K-Tech's site, around £4k

£3750- £4250 for basic throttle bodies on a 172

sounds good to me too.. But still wondering how it works? And would you need to remap?

Yeah 4 k ish on K-tec i think.

you need a stand alone ECU (which is included in our kit)

1 throttle body = 70mm diameter, ie you can get a certain amount of air through it, plus you then have the length of the inlet

4 throttle bodies = 45-48mm each, but you have 4 of them whats your "total" throttle area now?? MUCHOS bigger, plus your inlet length is now muchos shorter = good

simple explanation, but gives you the basics
