Sorry I knew I said I was going down to the track but it looks like I'm way too short on money. I have to wait till next payday

AssC8, no problem. Let me know how the break in goes and if you have any questions!

BigNasty, thanks for your interest! Looks like you've been runnning stuff that we brought in for many years, appreciate the support! Regarding the pipes I think thAT if you look back around page 3 or 4 you will see a post fro
our finish importer who was testing with the 2050. Also think that Mo put up a post on some testing that he did with one also. Think the consensus was that it was not bad if memory serves me correctly.

smb17, no worries every ones money is tight nowerdays! Think we both need to start hanging out with BigNasty, strippers pay for all his stuff! ;-)

I'm rebuilding my Lamberto Callari gold head B-7 I believe these are the same exact engines as werks? I was just wondering if WRXTL21070010]WRXTL21090120]will fit this engine. I also run a B-7 Pro This has been the best engine I have ran.I wish I never tried NR nothing but flame outs!!The B-5 will be the next engine I buy. Maybe Santa will be nice to me this year? But,only if I'm nice to her....

Anyone wanna buy me fuel and tires!? ILL BE YOUR BEST FRIEND!!!


Break in went very well. I'm disappointed that I can't afford time at the track for the next couple weeks.

First race with the B5 and i was totally impressed!!!! Ran way better than i thought it would. Only thing is that i was only able to get roughly 8.5 minutes a tank. I was using a sts 0403 pipe which i believe is a low end pipe judging by how long it is. But i only have roughly half a gallon on the motor maybe get better with a little more fuel thru it? Next time gonna try a jp-3 or jp-4 and carbon clutch shoes. The temps were 240 to 260.

How did you tune the low end?

I ordered my B5 last night. I hope that I have found a new engine to run for the next couple of seasons.

I really like the B5. It definitely has more bottom than the V-spec I'm not sure about the top end I haven't ran around any cars yet to compare. I think I MIGHT be able to make it to the track on Thursday and I'll be able to give more details on it. So far I love it. It holds a tune very well. So far no complaints. Ron you have like 3 PM's from me =D

I got around 8.5 minutes with my B5/2013/P4 at the Farm saturday, probably closer to 9 later in the day after I leaned it. At least a minute better than the Ninja. The motor ran great all day, first race in a while and a decent finish in pro, no complaints so far. The 2013 is soft though man got t-boned on the stinger.

How does this motor compare with the Mugen Ninja as far as run time and power, Has anyone run both? Thanks

This engine is a monster!!! I tuned one for my buddy this weekend at the Pro Series South 3rd round, an he was lighting it up on the track. The engine seemed to like the bottom end to be a little fat, because the more we fatten the bottom the better it got. We ran it around 215 to 220 an it totally ripped!!! He could go 10 minutes in the D8T if he needed to, but we decided to pit at 8 or 10 if he was behind. We ran the OD97T, 25% Byrons, 2013 pipe, and carbon shoes with 1.0 springs.

yes the motor is awesome...and yes I like the bigboy pipe for sure....
ran at a proseries race this weekend and the motor was awesome, tunes easy and was one of if not the fastest thing there running it around 230 range.. qualifyed 5th in pro made my way up to second then got completely violated in a 180 turn and had to come off the track to get fixed then came back and got 6th only due to being I think the only guy who could go 10 minutes so I eliminated a pitstop to make up ground...this B5 is awesome, and although it doesnt sound like a 2013 it still sounds awesome with the bigboy!!!!
but as someone mentioned yes it does seem to like the bottom a hair fat
I believe I am 1 turn out from flush but thats just my settings for where I was

I know what you mean about the 2013 I have seen some get bent up, I personally didnt feel the 2050 was the best pipe but it will get it around the track ok
my first choice so far is the bigboy
second is the GRP
third is the jp-3

Yes, the rod and rear bearing will work with the older Collari engines.

First weekend with the B5 on the track the engine ran great. Runtime was very very good with the 2013. The engine still has a tight feel to me on the track but that kept getting better as the day went on and I got more fuel through it. I did switch from a P4 to the P3 plug and liked the hotter P3 plug better.
