Ok, back to Jreds...70ccs. What are the models from current back a few generations?

Current model is the 2172 (Same as Husqvarna 372xp Xtorq)
One back is the 2171 (same as Husqvarna 372xp)
Two back is the 2071 (same as Husqvarna 371xp)
Three back the 670 Champ/SuperII is the closest at 66.8cc (Similar but not the same as 268xp)
Four back would be the 670/670 Super (Sort of a cross between the 266xp and 268xp)
Then your back to pure Jonsereds with the 70E.

Those are the facts, now for the opinion. All great saws! The 670 family of saws are probably my favorite saws period.

Oh man......friend of mine had the same thing only it was the Challenger ......same difference.....his was automatic.....needed both hands on the wheel!!.....what a brutus piece of equipment. LOL my first car was a 65 Cuda......but was not pushing anyway near that kind of power!!!

You had two things to worry about racing; keeping the 'cuda in a staright line with all that torque step and making sure the other guy didn't lose control and come into your lane.....lol!

These newer iterations like the Hellcats are supposed to eat the older iron....maybe, but I don't think it's the same visceral sensation. Kinda like crotch rockets against V-twin motorcycles.

I think you're right....and most of the new stuff is crazy fast especially the turbo charged stuff.....but it's not the same as the axel snapping, u-joint breaking power of before....but in the end some of the new stuff is really fast especially on the top end. Just as a for instance....the bride drives a late model Saab 9-5...2.3 ltr 4 banger...280 horse...Mitsubishi high pressure turbo...5 spd auto with steering wheel paddle shifters. We were on a road trip...I was driving, she was reading the owners manual and got the section on the turbo and the book says "once you reach 155mph you will notice that from then on you can no longer crowd the turbo gauge into the red zone.....this is a safety feature". I have no idea if it's true or not...nor will I ever find out....but I expect it is. I've had it to about a buck thirty with one gear left and no where near close to red line. In the old days you would have had to have some serious cubic inches to get a road car to 155 plus.......not a four door sedan with a 2300cc motor.......engines have come a long way in the last 30 years. Just no where near as impressive as big block power....and they certainly lack the sound....like the difference between Jap multis and a big v twin as you said.

Lol...I can beleive that about the newer sedans! Funny bit about 'crowding the turbo gauge into the red zone'. It's like that tired old argument where many say the 440 six-pack is as fast or faster than the 426 Hemi. Those arguments are always started by somebody that's never pushed a 426...basically a detuned track race motor for the street, it had the ability to keep pushing those old sleds until your balls dropped off. Nothing like it except maybe those 427 Ford side oilers that went into the SC Cobras. I never could find a 427 SC Cobra to race...kinda of a rare bird to see back then. But I raced about everything else that was factory made. The ones that you thought would give you trouble, didn't. But the occasional sleeper would....the guy that wouldn't let me see under the hood etc. Still, nobody ever came closer than a half-car length at the 1/4. We had a course laid out in the country on a flat piece of back road. Sheriff didn't care as long as nobody got killed and we cleaned up our mess...just farm land, no one to complain. The road looked like a airport tarmac with all the rubber laid...lol. They did eventually run all the kid racers out.

A friend of mine bought a newer Triump crotch rocket and had me ride it home because he didn't have his motorcycle endorsement yet. I thought my Susuki V-Twin 1400 was fast. Man...that Triump hit 130mph wihout breaking a sweat. I could feel it get up on that power band around 90mph or so and GO! Fastest I've been on a bike and it had a lot more top end left. No wonder the young lions get in trouble with these. In fact the dude he bought it from had almost lost his license with it.....lol!

Yep.....I have ridden the same 59 Pan Head dresser for 40 yrs.....many mods and rebuilds....replaced the speedo at the first 100,000 miles. Then I bought a Ducati 900 Super Sport...whole different world but with a similar sound. I then realized that was the "Sportster" of the Ducati world...not their big bike.....so.....I bought a beautiful 916 Super Bike....only 12cc bigger but FI, four valve, water cooled, six speed....stock but piped and chipped...I liked the 900 because I knew where the edges were...when you had pull and when the power band started to flatten out.....sensible unit. The super bike was all together different...edges were hard to find. I'd owned the bike about a month and one Sunday morning I decided to find where the rev limiter cut in. So I got out on US RT 1....no traffic....I took off in number one and spun her up about 8 grand snickked number two rolled her to the stop.....weeelllll.....we really got under way.....I glanced down at the instrumentation....was turning 11,500 at just about 105 MPH in second gear of six....I couldn't take it...had to shift.....no rev limiter was harmed nor activated .....that bike will pull the front wheel up just passing a car and you wouldn't even know it until you got off the wick and you felt the front wheel come back to tar.....and by now Ducati have gone way past the old 916.....crazy ****....I still have the panhead for when I want enjoy the ride, not be thrilled by it.....LOL!!

Oh and to keep this on the Jonsereds topic.....Ducatis have nikasil plated cyls just like Jonsereds saws......and some of the late 630 Super II and 670 Champs came with Ducati ign. coils!!! And well....real Ducatis are RED too.
 

Great article....so if I'm reading it correctly, we (US) invented the process and the Germans took it over on a large scale with ten yrs of R&D? I don't see any mention of Mercedes but the article is geared toward smaller engine cylinders.

Be great if we had the name of a reputable Nikasil plating company in NA that was willing to fool with chainsaw jugs....?

Mercedes first used it in the C111 rotary Wankel engine as did NSU in theirs.

Mahle held the patent on it if some other stuff I read is correct. European patents are much harder to track down than NA ones so I didn't bother to try.
 
Ahhh....the ill-fated C111. Kept waiting for that car to become a production model. Just became a test platform for MB innovations. It really would have been the first 200mph 'supercar' (third variant with a turbocharged diesel), if it had been released to the public. I always thought the car was uber cool.

‘72 Olds 442: Silver, 4-speed, stolen, recovered, sold for parts

‘67 GTX convertible clone: built from a Satellite, 383, 727, Silver with white interior and black top. Amazing car, lots of fun and countless adventures in the backseat with young ladies. Regret selling it.

‘69 Roadrunner: 440, 727, Dana 60, stupid fast rust bucket. In typical young male fashion I built the hell out of the engine/trans/rear but neglected the brakes/suspension/.etc. scared the piss out of myself one day when i did a pirouette at about 100mph on the highway. Parked the car on the side of the highway, walked to the exit ramp, called my dad from a pay phone to come pick me up. Never drove the car again; posted for sale the next day and sold at a loss.

‘74 El Dorado: big, fat, ugly, 2.73 gears and was like driving your sofa down the road. Purchased for $200. Fun while it was around.

‘74 Duster: OEM 318 cracked a cylinder wall and was replaced with a second hand Diamondback 408 stroker (11.2, Edelbrock heads p/p and decked, 1050 Dominator, enormous cam, roller rockers, 1 3/4 ceramic headers to 3” true duals) 727 with 3250 Ultimate Convertor Concepts stall, narrowed 8 3/4 with 4.30s, partially hidden cage with full backseat. Car was stupid quick (10.49 @ 132 mph 1/4 mile on race gas and cheater slicks). Was daily driver when I was stationed in Beaufort, SC, the wife used to take it to the commissary on Parris Island to get groceries. Hit a deer on the way home from a car show, only dented the bumper. Survived 2 hurricanes in NC before being sold.

Next car will be a ‘69 or a ‘68 Dart with a big block. Since I am a professional cripple now it will be an auto.
 
340 is fun in the dodges too. Had a 68 barracuda that way. Just couldn't find 4sp tyannies cheap put a 3spd in was never an issue again.
 
Nobody believes me but.....there was a rich kid in HS who’s father owned a big Chrysler dealership. Almost every day he brought the baddest of the bad stock Mopars to school. Terrible driver, ran into a bridge with a Roadrunner. Didn’t kill him but his dad killed giving him cars to drive.

Anyway......one day he brought a yellow & white trimmed Duster to school that said on the side graphics; 1/4 Mile Duster. It had a raised spoiler in the rear, but unlike the Superbird. I tell this story and nobody corroborates it. But I saw it with my own eyes. I would never race him with my ‘cuda because he was such an awful driver. He let me drive some of his cars however. He brought a blue ‘69 Roadrunner once with a Hemi and what sounded like a full race cam. I didn’t get to drive that one. My guess was that it was a customer’s car because it was over a yr old at that time. Heck, he couldn’t even keep it idling and kept stalling it with the competition clutch it had. That kid was a runnin’ joke around school. We loved the cars though....lol!
