got a side DDM pipe. I want more RPMS

[brad1161]

anyone take the side bleed and remove it and put a exit near the end of the pipe? Will this help on higher rpms? I do alot of parking lot racing. street tires

 

[Deluge]

You could gear it a little higher, as well. I've never seen anyone convert a side bleed to an end bleed.

The stingers protrude into the expansion chamber. I would hate to ruin a pipe. The end bleeds do promote top end. If you are running the factory engine you will be limited on rpms. A race ported engine revs much higher.

 

[Deluge]

Agreed. Not worth ruining the pipe to find out.

Time to do some engine work.

 

[brad1161]

ok. what top end kit do you recommend? Local hobby shop has a race ported kit for 30.5 comes with piston, cylinder,and gasket and new plug for $140

 

[rchobby89]

do they have a name on it like who did the work like esp or rcmk

I run an ESP 30.5 Champ port. It's a beast.

ESP Mod/ESP CHAMPIONSHIP PORTED GP290 36mm kit +2MM

You don't need the crank. The stock engine already has a +2mm crank.

Pick up some of these cylinder gaskets, as well. The gasket that comes in the kit is lame.

Yes ESP is the one

I'd go with the champ port. It's going to be a little cheaper from DDM when you use the 'HBF' discount code. Plus, you'll need to order those gaskets, anyway. May as well get them at the same time.

 

[brad1161]

How much more rps do you think? Little, lot?

 

[Deluge]

It's a screamer, dude. Plus you'll have plenty of torque, so you can run a higher gear ratio. Which will help increase top end.

i know my lhs carries the champ ported esp and the head gaskets i would contact them and see witch headkit it is that way you wouldn't have to wait on the shiping price wise even with the cupon code you are only looking at around a 7$ savings in my opinion not having to wait a week for shiping is worth the 7$ lol

It is also good to support your community.

DDM gets their stuff out quick. 2-3 days, tops.

I would not save the $7. My problem is I keep shopping to try for the $100 and free shipping every time. LOL

A lot! The factory engine can hit 14,000. My OBR is pushing 20,000. Its not apples to apples though. The OBR is a 27.2cc which are known to rev to the moon.

Yep...

They get an "A" in my book. Great service.

Do you have a tach?

Just one of those little ones DDM has.
