Default Quick question: Novarossi Roma vs 28-8 for Bashing Truggy

Quick question, Iíve searched a bunch and have narrowed it down to either a .25 Roma or a .28 28-8 and either a 41001 or 41032 manifold with a 9886 pipe. Truck is only for bashing so fuel mileage doesnít matter, just power. Any recommendation on which engine to go with?

I haven’t had a Roma, but I do have a 28-8. It is stupid powerful.

I've never seen/heard anyone mention the Roma being more powerful than the 28-8. The only engines that were mentioned as being slightly more powerful in stock form were the Picco .28 and LRP 32. According to Neal, if they're modded, the Nova drastically separates itself from the Picco because it can rev so much higher. The LRP would be nicer if it were made to the same standards as the Picco and Nova.

If I may add a question of my own..

Where does the nova 28-7 fit into the rankings?(for bashing) Specifically, compared to the 28-8.

I've asked other places and never got an answer from someone with experience with both Novas.

Front what I can gather from reading about 300 pages of the nova thread and various other threads, the 28-8 was originally the Rex version of the Nova 28-7, with the only difference being the 8 port sleeve as opposed to the 7 port sleeve, but they stopped making the Rex engine and call it a Nova engine now. So basically, the Nova 28-8 is just a Rex 28-8 with a purple head which is just a Nova 28-7 with the 8 port sleeve. They very similar but the 28-8 is Ďsupposedí to have more top end, but I doubt anyone could tell the difference between a 7 port and an 8 port. (4 port to 5 port is pretty noticeable, but 7-8 not so much)

Do some reading about 2-stroke technology and come to the conclusion that port count has not much to do with the performance. If you did notice the difference between 4 and 5 ports then other factors were causing that.

I can say that I’ve seen a stock 28-8 run next to a modified 28-8. A bone stock 28-8 indeed has crazy top end - more than a Picco .28 stock vs. stock IMO. Changing the timings adds even more top end and makes them really wake up. A 28-8 in a truggy is a bit much as I’ve seen, but if you’re after stupid power, then you wouldn’t be disappointed. The 28-8 is a stellar engine regardless of how many ports it has. It revs like no other .28 I’ve seen stock out of the box.

And OS is made to a completely different level than a Nova. You would downgrade in quality buying OS over Novarossi. IMVHO.

I have ran them all, I have had bad experiences with 2 Romaís that I have owned, rear bearing failure.. turns out the block was slightly mid aligned causing Pre nature rear bearing failure.. this is on 2 Romaís I had..(these were early ones, maybe it was fixed)

then had an OS 28 ran for 5 gallons, sold it.. got it back in a deal about 1 year later, and ran another 3 gallons through it.. never once opened or serviced.

there will be be horror stories from all big engine manufacturers..

fact is the OS28 is a dream to drive, smooth but powerful.

I'm just providing options

Those failed Nova bearings - were they ceramics by chance? It seems that the Ceramics are nowhere near as durable as a good steel bearing... then again, OS has used substandard quality bearings in the past... nobody is immune to quality issues whenever parts manufacturing is outsourced.
