Upgrading my 421 serval


Recommended Posts

I will do the dyno tests on my small ATV dyno. Same dyno all my stock cyl and cubs are done on. I run 19" tires with 17-39 gearing. The dyno passes will be made in 6 th gear. I will be checking AFR on each pipe. I will do a as cast set of runs and a ported set of runs. Domes will be a pump gas setup. Same domes will be used for all testing. This may not be the best for all pipes but its a general test. Cam

That dyno setup should be good. I hate for anyone to get their pipes scratched swapping out pipes, I have a set of in-frame test pipes you can test with.

 

Ragun, I have not tested ceramic or power coatings for power gains or loses.

After much thought, ill be doing chrome. I'll just have to keep them up and not be lazy like i used to be.

 

Do you make snipers for big bore engines and have a test set for that? I'm doing a 10mil super serval. Id love to see what they can do. I just read the 10 page passion thread trying to learn some more info but that thread turned to crap. I do understand snipers are designed with a certain size engine/set up in mind which mine wont be.

Gary, I think Cam said he would be ready in 2-3 weeks on the 10mm motor. That would be awesome if you'd send a set out. I'll PM you some info.

Hmmm see I dont check the HQ for a weekend and this is what I miss. I will make sure I am on hand for this test. Should be interesting to say the least. I have a clean one owner set of Shears we can use if needed  :rotflmao:

would the pipes you are loaning be the same pipes as your standard pipe? or are they more suited toward a lower rpm motor?

Cameron, when you post the sheets have the notes, run conditions and correction factor on the sheet for reference....Thanks

 

 

Ragun, I put a 1 inch ID stinger on all big bore gas engines and a lot of alcohol engines.

 

 

Ims, this set is standard with removable stingers.

O fuck if you are coming back to witness this then I am not going to show up. Tyler tried to rape me last time he was there I had to get Dyno (Cameron's dog)  in attack mode to scare him off.
