new dyno numbers!
My 99 MR EM1 got retuned tonight finally. It had been running real poorly, especially at partial throttle. I took it to Slowmotion Motorsports, and C.Parrish hooked me up! 290whp/204whtq @9psi at 8K rpms. precision SC34 w/rc 550 injectors hondata s300.

WORD!!! drives like a champ, still waiting on my thrust washers that are on national backorder so i can put my built motor in thats sitting at Slowmotion now. GSR block 81.5mm CP 9.5:1 Manley turbo tuff rods w/LS crank should be tuning to 16-19lbs...or when the turbo maxes out, whatever comes first!!!

Nice numbers. As for the manifolds I would not spend my money on them. For one they only give a 2 year warranty against cracking and they charge 850 for a ramhorn?? 950 for topmount?? those prices are ridiculously high for a manifold with a 2 year warranty. They obviously don't stand behind their work if they don't offer lifetime.
SlowMotion does great work. Offering a "lifetime" warranty is kind of pointless anyways. You tell me how many of you will still be using the same manifold 4 years from now, let alone 10, 20, or 30...
Straightlinespecialties.com they offer high quality manifolds, my ram horn was $695 with a lifetime warranty........it fit great, i dont know if dyno numbers will improve that much when i get re-tuned but very good customer service on both manifolds i bought from them. i dont know how to post pics on here, but you can look at my site for them.
SLS manifolds!
