I am not associated with the group alone, I'm just building a muffler which they may use up coming calendar year. So style and design is simply conceptual at this stage.
Furthermore, motor displacement doesn’t truly subject either. Most engines burn up about the exact degree of gas to make exactly the same degree of horsepower, which means the amount and temperate of exhaust gases over a 400hp 4.0L are approximately the same as a 400hp 6.8L.
mike – You’re correct. I am able to’t realize that information either…the oldsters who style headers, and so forth. don’t prefer to share.
Jason, my apologies for functioning you from the department of redundancy Section. LOL! When I read the thread I did so on my sensible mobile phone an the replies were reversed so I only observed your second reply.
2nd, the “butt dyno” – i.e. your own evaluation of ability – just isn’t really precise. It’s difficult to explain to how fast one thing is simply by come to feel.
I might love to locate a Completely ready designed exhaust for this automobile but the sole one I could obtain was by Apexi – it was just the muffler and only two-three/eight″. I’m planning to establish a new method from your Y-Pipe again – new cat resonator and muffler. There is de facto only one bend exactly where it goes under the rear control arms so I'll just weld it up from mandrel bent tubing.
I am able to’t consider this thread has become happening for 5+decades! Many thanks Jason! After reading via the entire posts, I don’t Assume my question has been lined. I've a 71 Blazer using a 350 SBC which i estimate being while in the 350hp variety.
I'm More hints attempting to exercise routine the diameter for my muffler for just a yamaha YZF-R6 motor (599 cc). This engine is getting used to ability a race vehicle in my university.
Also, from what I read from other web sites, some seem to Stick to the mantra that greater is always superior for turbos as the many efficient inertia is used ip with the turbo and receiving the the exhaust out asap, enables the turbo to spool up earlier. what are your ideas on this?
Dean – I’m not a hundred% specified on the precise arrangement, but it looks like you’re mounting a dual program to your V8, with headers and every little thing. 1st I'd suggest which you request to discover a ‘in advance of and soon after’ dyno chart for that headers. At times headers take electrical power from The underside conclusion to include energy to the highest…it raises peak HP, but it really can make your car much less entertaining on the street.
My problem is not really HP, it is actually destruction or long term harm on the motor, or soot gathering the the cat. As you could explain to, I haven't any expertise, I just study that a limited move just isn't good, but I don't have any approach to gauge if this is the non difficulty, compact trouble, or massive problem.
I retain resource coming back to this webpage, but something important has not been included and I am able to’t locate any where. Presented an exhaust gasoline outlet temp from a cylinder head, and say one.five″ pipe, How can you determine the loss of volume as being the exhaust cools?
i just had my exhaust pipes changed yesterday and I felt which i just rob some hp to my engine. I’m not nonetheless sure if I check out here received the incorrect experience, it's possible due to the sound or the vibration or whatever but I think the reaction and the peak energy on the engine is not as highly effective Evaluate on the stock exhaust. I have a 1995 Civic Eg D15 engine
Ed – Yes – a dual in / dual out (or dual in / one out) makes sense with a V6 pickup. I sent you an email concerning this also.
