End dumps

[yammieguy]

Do the power Inc end dumps have individual silencers not fastened together and no stamping on them? Also do the have half round pipe mounts on them that the other pipes lay on?

 

[yammieguy]

Also do not see any tabs on the manifolds for spring mounts, how do you fasten the pipes to manifolds on them?

 

[Tripp700]

The pipes that I use have the saddles that rest on the other pipes so they don't flop around once the springs are put on. The manifolds have holes on the flange for connecting the springs. Silencers are not fastened together and have no markings.

Au Contriare.... There might be a single can muffler for those pipes.. if one were to want to be trail quiet...

 

[yammieguy]

Bet that is a hard find!

 

[Scottanderson910]

Got one hangin around in my garage... Its going to replace the crackle cans once the trails around here open up.

 

[yammieguy]

Sure sure rub it in..lol

Anyone else hear of a power inc can for the SX 700 style end dump pipes? Ive been told only a few exist.

 

[srxman72]

I think I remember someone saying only three were ever made.

 

[yammieguy]

what rpm should these pipes run at? I had thought 8400 but see a power inc sheet in the tech pages that says around 7950?

 

[Scottanderson910]

I was told 8400. Can you post a link to that tech sheet? I cant seem to find it.

 

[yammieguy]

what are you running for gearing? I was thinking stock srx23\38 gearing which would come out at 109-110 mph or would this setup pull 24\38?

The power inc pipes that run 7950-8200rpm were the center dumps and
the end dumps ran at 8400rpm if I remember correctly.

 

[Scottanderson910]

Agreed, I'd say that spec sheet is for the center dumps. I believe those were the "trail performance pipes.

As for gearing, I'm still playing with that. Let me know what you get figured out..

 

[yammieguy]

I was thinking stock 98 Srx gearing but I don't know if this motor has the torque up top to pull it..

 

[yammieguy]

How about tempa flows? Anyone using one and is it worth it?

 

[The_Paragon]

SRX gearing is pretty tall for that. Stock SRX is 23/37 right? That would be 1:.64 ratio. Stock SX is probable like 23/40 or 22/39 which would be 1:.58 or .57
Quite a jump.
