Just saying there are always other choices. Andrew

#1- find a header that fits #2-buy the W2 flange #3cut the LA flange off and weld the W2 flange on Andrew

MT the ones on Jerry's ride`have to be the ones from post#6 not the ones a few posts up. Be careful. Andrew

Grasshopper (MT) If I have taught you anything it's only metal. Andrew

I know the need is there, I was talking about the pricing. I will be making a set for the missile, but if the product is to be made available to all of you, it has to make enough money to support the business. Andrew

OK, first of all how much was Laysons asking for headers, I called them and they actually called back and they said they did not know anything about them!??? I may be a position in a few months to start a business and was actually thinking about the header situation. I was thinking about a set...

Well I talked to the customer service @ Doug's and they hooked me up with the proper pic. Now about the price for these pipes.........$868.00!!!!!!!!! He said it was because it was a kit, and they did not offer just the headers without all the other stuff shown. MaMa didn't make me stupid enough...

I know the picture is generic and the flanges shown are for a chevy. It was the design of the pipes I was talking about. The listing is for specifically a 318-360 mopar LA for a 94-00 Dodge Ram1500. Andrew

Has anyone tried this Dougs header labeled 2WD truck? It is listed for use with 318-360. part # D4462. It looks like a happy medium between the tight truck headers and full length headers. Andrew

I'm interested in this as well. Andrew

Thanks Andew

Could someone post pics of the spitfire headers? Andrew

Mope, According to the engineers I have contacted the goal will be to have .25"-.5" of vacuum at the exhaust port. The system is adjustable in a number of places. Skybolt- READ THIS VERY CAREFULLY-- These engineers build and design motors for NASCAR, Sprint and Formula one vehicles, EVERY ONE...

First, GTX thanks, I was not trying to hijack the thread. Cave man, The object is not to propel the car with the system but to negate the exhaust systems faults and limitations. Mope, The system is based on a technology called 'Air Amplification" It utilizes compressed air and the 'Coanda"...

I still need some advice in generating spark at the rear of the car Andrew

375, good video. As he said the after burner adds thrust by injecting extra fuel into the final compressor stage causing an increase in RPMs=more thrust. Now in regards to an internal combustion engine, what do you think the effect would be of putting the exhaust system into negative pressure...

OK you guys will think Im crazy, ok the ones that already dont think Im that way. I need to know how to set up spark generation for a set of functional afterburners (not flame throwers). the spark plugs are there and I have the coils, I dont want to tie it to the dist in any way, I also have...

Tom, where did you get the vacuum actuators and what is their throw? I need a set for an exaust related project, very different from yours. Andrew

375, All that I researched confirms all that you have said. Illiminating the back pressure in the system will greatly increase velocity.Yeah it will get louder as well even with a muffler, but the benifits to effeciency and power would be worth the effort. IMHO. Andrew

Flyboy, the more i research this the less there is to back the keeping of any back pressure in the system. Please explain the physics of why you state dont get rid of it all. Then we can discuss how. Andrew

Even with just headers and tailpipes you have a phenomina called 'reversion' where a high pressure pulse is present in the headers when the exaust valve opens contaminating the incomming charge. The tuned aspect of headers minimizes the effect by scavenging but does not iliminate it. 18"...

Ok Guys, how do we eliminate all back pressure in the exaust system?
