wow... then again Inline Pro's manifold isn't a true log. It's more equal length then let's say a Ultimate Racing, so power gains should maybe be somewhere in the middle?

 

i got 525rwhp with the inline pro kit ...








and a built engine

 

yea the inline pro is a much better designed log style manifold, but u def could see more hp at the same boost with a tubular like the sidewinder from lovefab

 

[QUOTE=TeamSiRs2k,Jan 26 2006, 09:58 PM] wheres the proof of this??? I havn't seen any turbular numbers that made me be like

 

A lot has to do with the angles&time pulses hitting. A lot has to do with the material/metal. A lot has to do with measurements.

 

I think what some of us are trying to say is, we've seen no convincing numers. Yes, it would be incredibly convincing if you ran an 8psi tubular and log setups back-to-back on the dyno and could show measurable differences in power/torque/spool/etc.

 

The honda-thech thread I posted does just that. Back-to-back with log and tubular manifolds at the same psi(map).
Its not an s2k, but you get the idea(40HP gains in the powerband).

 

Where is said thread?

 

I went from an UR log manifold making around 290 whp and 192 lbft of tq with full stock timing at 7 psi. Now I have a tubular manifold and at 6.2 psi and very conservative timing(much less than I had before on the log mani) I'm at 332 whp and 217 lbft of tq. That's a 42 hp increase all over the powerband with almost 1 psi less of boost.

 

Man, that's almost impossible for me to believe. And there was absolutely nothing else changed at the time? Different intercooler, injectors, any tuning done?
