Guest Anonymous Posted May 12, 2001 Share Posted May 12, 2001 Ross -- If your polish job helps, how 'bout some insulation? Ceramic coating on headers is supposed to keep about 50% of the heat inside the pipe (as opposed to I-don't-know-how-much on an uncoated header). Just food for thought, and fodder for another great thread. Quote Link to comment Share on other sites More sharing options...
Modern Motorsports Ltd Posted May 12, 2001 Author Share Posted May 12, 2001 agreed/current headers are coated and so will be the new ones Quote Link to comment Share on other sites More sharing options...
Kevin Shasteen Posted May 13, 2001 Share Posted May 13, 2001 Ross, Apologize for the late response-I've been preoccupied this week.....Alright, so that I'm reading from the same page here; your intention is not to alter the intake's chambers but to merely smooth them down. In doing so-you're wanting to obtain cooler air temp's of the incoming air; Yes/No? So, it's air temp you're wanting to alter & not the speed/lack of speed of the airflow w/in the chamber's; Yes/No? BTW: my use of the word "Spacer Plate" was possibly an incorrect choice of words. I probably should've chosen "Insulator Plate" instead being fabricated b/t the TB & manifold. I also have Vizards book on modifying intake manifolds. He mentions where he has had success in blocking off the Exhaust Heat Risers & claims the engine still has sufficient heat to reach operating temp's; barring ambient temps reaching freezing & high humidity that an intake doesnt really need a heated cross over passage: reaching operating temp will obviously take a little longer as a result. Vizard has also welded steel plates to the bottom of his manifolds (alluminum manifolds) to deter the heat transfer from the hot oil. Just for posterity's sake here; why would you go to all this trouble to "Smooth" the intake chambers & not make any attempt at porting them? Would not one improving the airflow compliment the addt'l lowering of air temp & further improve "Density" & the "Ram-Air" effect of air entering the combustion chamber-would this not result in more power: Just Curious? Hope I helped you this time & not frustrated you! I hope you know I'm not on this board to frustrate anyone; no one enjoys the "bench racing" more than myself & I always look forward to discussing the dynamics of a performance process. Joe Mondello offers a porting kit for Cast Iron & Alluminum. His Catalogue#:PK 230 or 235. The first kit includes multiple carbide burrs w/upto 4" shanks. @ 100 abrasive rolls; 6 various shaped cutting stones. The second kit is for alluminum & uses carbide burrs w/8 flutes for faster cutting & less loading up; lubricant is also added. PK230 = $129.00 PK235 = $135.00 These prices were taken from my 1997 catalogue so prices may have varried slightly. Mondello's ph# 1800.237.8808. You might also check a PAW book; their kits are broken down to smaller kits & price reflects this. Their kits range from $20-$40 & dont include all the shanks & carbide cutters that the Mondello kits offered: PAW's number 1800.678.3000. Eastwood's site is WWW>Eastwood.Com; their kits range from $5 to $35 & refer's to the rolls & not carbide cutters. Aside from not having the carbide cutters advertised-I like Eastwoods breakdown of their kits better than PAW's or Mondello's.
