are you still running the boomba fuel rail? any thoughts about swapping it out for something with a larger ID? Just a thought since everything before the rail is -10 and the boomba rail is .5" Your lines are 38% larger than the rail. Just something i'd consider trying before selling the fuel system you already have, and would want it with the new system anyway. here's a pic for reference http://www.srtforums.com/forums/atta...1&d=1135015087
If the rail is .5" internal diameter, there is no need to change it. There isn't a neon on the planet that could max out a rail that big as it would be good for at lest 2000 hp.
they one in the pic ( my pic) is .480 id vs .780, but the real problem is the size of the fitting id.. a -6an which fits the boomba i.d. is .296 vs the -10an's .483 or 2.66 times the flow, fitting vs fitting.
Chris, I thought you said "the manifold isn't a restriction so why bother porting it" ??? Any reason why NOW your porting it out...
I had no plans in having it ported, as it is shows its not holding me back in power from what I can see. I got offered a deal on one to do some testing with and I accepted just too see if it helps any.

I plan on sticking with the same rail. I have a new setup already installed and ready for rollers coming Monday.

It just took a little sweet talking (and a good deal) to get him to change his mind. I know the tuners at AMS said that the mani isn't holding things back, but I plan on proving them all wrong.
I would be happy with +20hp from the ported IM, but I am hoping for more. I mean even those with stock turbos that are no where near the CFM that Chris is seeing, are picking up 10-12hp on average.... anywho, results will be shared soon.
So you are saying that it had a stock unport-matched to a full race ported head? so it had like a .250 inch lip all the way around?
Well not gasket matched from what AMS has stated. I called in prior to sending the IM to them for testing so it would be a match. I was told that is was slightly larger than stock. My IM for this test is portmatched at this point.
His manifold is untouched at the moment. The curves on the dyno graph are pretty smooth and dont show any signs of the manifold holding it back. Last night we ran it upwards of 7500 RPM and she seems to be happy right in that area. Im sure we could start to spin it higher but It just doesnt seem necessary as the power band is soo meaty now and that it peaks at 7000.
The ported manifold might help out a little but nothing insane. The stock design is actually very well done. We are not one to stop progress though and we have been wrong before. Now that we have the HP where we want it (made some more Hp last night) we will test the ported manifold. It might not get done before christmas but we will do our best.
