Car: 86 iroc, 87 iroc, 89 iroc, 89 formula, 84 supra, 85 trans am. The method can include construction of a boom tube exhaust pipe having a center spacer rib and/or a pair of lateral spacer ribs each disposed laterally outside one of the respective structural ribs. Crossover pipe 759 allows exhaust gasses to crossover between secondary exhaust pipes 725 and 728 to better balance the exhaust gas pressures therein during the firing of the cylinders of engine 701 dumping exhaust gasses alternately through headers 707 and 710 through respective secondary exhaust pipes 725 and 728 as to reduce exhaust gas backpressure to engine 701 by allowing more efficient exiting of exhaust gasses. They provide a slight decibel reduction while using Naca ducts to reduce more backpressure than dumps. Description: I have a used Nascar Boom Tube exhaust for sale.

I had to extend the crossover to the correct width of the longtubes I had on my car. The rat rodders in my area love these exhausts, they range from $125 to $150 used.
The boom tubes are the fancy flat exhaust tip. Aero Exhaust Morgan-McClure NASCAR Crew Shirt Size Large. The single inlet version diverges to laterally opposite sides of the motor vehicle and the dual inlet version exits to one side of the motor vehicle. 5" system that goes from collector to exit. Ground clearance is critical on the Cup car as well as the aero effect the flat tubes might provide. Main funnel passageways 479 and 482, and main mixing passageway 497 allow the exhaust gasses to mix or combine and expand prior to exiting through a flattened outlet opening 518. Examples of such baffle arrangements in single and dual inlet versions include laterally extending, longitudinally spaced flat baffle plates which alternately extend from opposite sides of the casing with respective gaps between the free ends thereof and the opposite side portion of the casing for exhaust gasses to pass thereby so as to route the exhaust gases side-to-side in a generally horizontal plane. 5, 824, 972 issued to me Oct. 20, 1998 titled "Acoustic Muffler" is hereby incorporated by reference into this patent application. That helps drop CG height.
The method can be practiced wherein the welding of the rib to the respective upper and lower half shells is of the resistance spot welding type, or by using half shells each of which include a plurality of longitudinally extending plug weld holes such as round holes or slots punched therethrough and plug welding the rib to the respective upper and lower half shells through the plug weld holes. Dropship items are non-stocking items that are shipped directly from our supplier to you. Magnaflow Exhaust System Muffler LANYARD. The half shells can be asymmetrical in cross-section, have overlapping lateral or longitudinal edges, be left and right halves rather than upper and lower halves, be made of a single stamp formed piece of sheet metal which includes halves of the inlet and body together, include integrally stamp formed ribs therein which can be spot welded to the mating half shell or mating ribs thereof which extend only part-way vertically through the body and/or inlet of the boom tube exhaust pipe. 17, rotated ninety degrees counter-clockwise, showing the details of the typical mounting of the exhaust pipe to the chassis of the car; FIG. 5 inch after the last major bend beyond the muffler outlet. A plurality of such rectangular tubes (or square tubes) can be welded together side-by-side in place of the single rectangular tube with the sheet metal side pieces welded to the two outermost tubes to form a thin profile, generally flattened tubular body of greater width than using a single rectangular tube. This technology was developed in the 60s by at leat one OEM but used sparingly. Whereas this invention is here illustrated and described with reference to embodiments thereof presently contemplated as the best mode of carrying out such invention in actual practice, it is to be understood that various changes may be made in adapting the invention to different embodiments without departing from the broader inventive concepts disclosed herein and comprehended by the claims that follow. Other such examples of such arrangements of baffle plates include such as for the dual inlet version a pair of such above examples, comprising two complete sets of baffle plates as described in the previous examples, one generally centered about the longitudinal centerline of each of the respective inlets, the innermost plates of which can terminate at the center spacer rib rather than the side portion of casing or simply terminate such that exhaust gasses can pass therearound. The dual inlets can be integrally formed together and with the body from a single piece half shell of sheet metal.
SUMMARY OF THE INVENTION. A six cylinder gasoline engine 701 powers stock car 689 through a drive train 704. If I recall, Cup cars try to dump their exhaust in a low pressure area of the car when it's at speed. All that surface causes flow restriction, so the cross-sectional area seems just about right for the inlet. Looking at that picture I get a kick out of seeing an old T-10 tranny those things havent been ran in 20 years... Boom tubes. Dr. Gas Exhaust Components Decal Sticker Racing NASCAR IROC Hot Rod Car Auto. I think we'll start seeing more of this. I know that a gradual expasion like that is best for airflow when you are trying to get optimum flow from/to big catalytic converters, but would you get the expansion = high pressure "plug" that oldsstroker was threorizing about?

The structural rib comprises a piece of sheet metal formed so as to have a longitudinally-extending web which interconnects respective laterally outwardly bent upper and lower legs or flanges which extend generally normally therefrom, such as forming a C-shaped channel cross-section. Switch to Hybrid Mode. A center spacer rib can extend generally longitudinally through the body generally laterally centered therein between the respective inlets and structural ribs.

Exhaust gases enter exhaust pipe 20 through an oval shaped inlet opening 101 of inlet 23 formed by upper and lower front half shells 32 and 35 into a main funnel passageway 104 formed thereby having a pair of individual passageways 107 and 110 interconnected by exhaust gas cross-over holes 89. A single larger one could create more downforce.??????????????????????????????????????????????????????????????? 18, a fragmentary lateral vertical sectional view taken on the line 18—18 of FIG.
This is for my street car/toy with a full cage that I plan on dragging out to every motorsport event that my time and $ will allow. Does anyone have these? The portion of the structural rib which extends into the inlet is tapered so as to span between an upper and a lower inside surface of the inlet, such tapered portion being formed such as by splitting the upper and/or the lower leg or flange and forming at an angle relative to the remainder thereof. It is designed to route hot exhaust gases, hazardous fumes, and noise out and away from the vehicle as well as the driver. 75" primary HEADERS w/ 3" collectors. Dr. Gas and BSR probably have a lot of info available about the outlet design and advantages / tuning, but my guess is that you will not see anything at normal highway speeds. Results matching fewer words: nascar exhaust. As such, the bend radius of the respective side portions of the tubular inlet typically decreases uniformly from the first to second end thereof unlike prior art inlets. 17, a bottom plan view taken on the line 17—17 of FIG.
