Cylinder kit TS1 225 Mark Broadhurst Race-Tour tuning

[GPMatt]

Sorry Mag....

I have been on 3 or four different Dyno's. My opinions are based on a standard TS1 with a 58mm stroke crank having between 17 and 20bhp, not a 60mm crank- and not 25bhp as std.

no offence meant, i've read your happy with your motor, but by bolting that kit on and setting it up right, nobody can achieve 30bhp. it needs a lot of work.

I think the point of this thread was for the MB tuned kit. You'd have to be mental to spend that kind of money and not match the casing, fit decent exhaust, crank, carb, etc and this done you will get a different result to a standard kit bolted straight on. So yes a standard kit is nearer to 20hp but a correctly set up tuned kit should give a lot more.

ive got a broadhurst tuned monza barrell,if this qualifies for
the thread i will try and find my dyno graph out, ,

[Philipp]

hello,

i have recently added my dyno graph (amerschläger P4 dyno) to the Lambretta dyno graph posting area. it is the said Racetour tuned barrel with 30mm Mikuni, 60mm bgm crank, MB piston, MB head and with Sito clubman exhaust. the casings are unmatched and it gave 22.5 hp.

i would bet that if set up as recommended by Mark you'll get (roughly) the predicted power. it is all back to back and dyno tested and i can't praise the quality of Mark's tuning work high enough.

cheers philipp

Mate of mine has just had TS1 built from the ground up by JB and the road/race tuned by them. Result was 23bh on there dyno. bear in mind this wasnt giving it the beans as its only just been built. I will find out the cost of that and whatwas included if this helps?

This kit with a 58mm crank comes to £1176,76. Plus having your cases match £?. Dac is only £1550 for a basic kit.

I've dynoed quite a few of these kits with various exhausts all built by Chris Sturgis.
Our dyno reads a little lower than Broadys and a bit higher than say JBs.
Depending on exhaust between 25 and 27hp is the norm.
By comparison an unported well put together TS1 makes 19/20hp on our dyno.
They make a lot of torque as well though and lastly and most importantly they are very very quick on the road.
Peak hp and peak torque mean absolutely nothing though its the area under the curve which matters.

Thanks to all, and come on with the feedbacks. What touring speed could I get with this kit? JL4 or JL3 could be the best pipes for this kit?

im sure mr Broadhurst would recomend his!!!i personally think weather its a std ts1 or a tuned one the "touring"speed as you put it wouldnt be any different...if your running a 4.80 ratio as i am youd expect 70mph at 7000 revs,the exhaust and state of tune would dictate how the motor transfers its power(how it feels to ride)

I have built five engines useing the ts1 rt tune by M.B and had each one on the dyno at diablo and set up by Al, each one has been different in the parts that have been used to build them .
The highest figure was 27.4 and 20. ft lbs with the lowest one being 26.8 and 21ft lbs. The big difference is how fast they are on the road, the power comes in faster then R.B engines tested on the same dyno.These dyno figures could be different on other dynos, its more important to stick to one dyno when building and testing engines.The cheaper built engine was just as powerfull as the more expensive one but probably wouldnt last as long.
