Default Ofna DM1 with LRP .30x what pipe

I just put an LRP .30x that is the competition non pull start with 7 ports in my OFna DM1. I just broke it in and without a full race tune this engine is awesome.

I would like to get a race pipe for it instead of the pipe that I'm using from the original Force 28 engine.

Will be used for club racing medium to long tracks. The engine has plenty of low end, so if I improve anything it should be the mid and higher rpm range.

What are your suggestions.

I think an 086 is the way to go.....

I would say either a 2052, or a 2015.
I am using a 2052 on my DM1, and it pulls all the way through the end of the straight.
A 2015 pipe will give you more top end over the 2052 though.
I use three 2015 pipes on my 1/8th scale cars, and the top end is great

Default thanks

Sorry that I did not get back sooner. Too many posts on too many forums to keep up.

thanks for all the help. I will be making a winter project of LRP's in my DM1 and GT2 for the winter, new pipes, upgraded brakes, Ipanema tranny in the GT2, suspension tweaks on both and new bodies.


Thanks
Jim

Hey brc358,
Will the 2052 and 2015 exhaust pipes work well for both .21 and .30 size engines?
I thought the .28/.30 sized engines needed larger exhaust systems than the .21's.

I run the 2052 pipe in my modified Pico in my DM1, but a very good friend of mine runs a 30 engine, and he also uses the 2052.
The 2015 will give more top end, while the 2052 will give more torque.
He told me that he is changing from the 30 back to a modified 21 though, so he will most likely use the the same 2052, or use a 2015.
So I was going off of what I know he uses.
The 30 size engines are beasts for sure, but they cant hang with some of the high reving modified 21s. They run out of power about 3/4 down the back straight, but the torque is great.

If you are interested in higher acceleration and top speed check out the graphite GT2 chassis at www.maxvelocityracing.com. There is a whole graphite kit for the GT and GT2

The pipes are NovaRossi brand. You could begin your search with your favorite retailers.

I would run the 2052 with a jp racing conical short header. The header being the key to more rpm and overall hp. You should find the header on ebay. It makes the big engines into screamers.

Default DM1 pipe for LRP engine.

Through some dealings I got an 086 pipe cheap. Any other opinions on that?


Thanks

Jim

+1 on the ofna 095. It looks exactly like the original but instead of a silicone coupler it uses the gasket and spring type.
Run the same motor and the 095 pipe. I use mine for drag racing at 150 feet I hit about 55 60 mph.
