CARPENTER'S NEW STREET EXHAUST!!!

[knecum]

Carpenter Racing is excited to announce a new innovation in Suzuki Hayabusa performance exhaust systems – the InsideWinder

The InsideWinder is a state-of-the-art, 4-into-1 megaphone sidewinder exhaust system that fits inside the stock Hayabusa bodywork with no modifications required. In fact, the system fits on dead-stock Hayabusas of all model years. No special pans or cylinder head modifications are required.

And we can boldly state that this system makes more power than any Hayabusa street pipe on the market.

Bob Carpenter designed and built the first-ever sidewinder exhaust system in 1980 and in doing so, changed the face of NHRA Pro Stock Motorcycle drag racing to this day. Carpenter Racing continues to innovate with the all-new InsideWinder that works for both street and track applications.

“We have led performance innovations with the Hayabusa for years so it was obvious that we should offer a new performance exhaust system,” said Bob Carpenter. “We thought outside the box with this system and did something completely different from what is currently offered in the market.”

Current exhaust systems use a stepped header size design to increase the pipe diameter. This design was developed as a way to fit a large-diameter pipe to the head but is not the way to make the most horsepower. Our large-diameter, 1-3/4 inch header pipes hold a consistent size from the cylinder head to the merged 4-into-1 collector. This allows us to get the most out of both a stock head and a head with a ported exhaust.

The results of this new engineering are impressive. “We have gained 3.5 horsepower over the next best pipe in the market on a stock head,” said Carpenter. “Our system can also take advantage of a more aggressive exhaust port. On a ported head we gain nine horsepower over their pipes. Their stepped designs cannot take true advantage of a ported exhaust port like ours can.”

The InsideWinder system is constructed entirely of stainless steel and is available in polished or brushed finishes. The long megaphone has a removable 3” diameter muffler core. All fittings and mounting hardware are included.

*** Currently in production. Expected delivery late February ***

This would be a good choice for a big stroker also ? I mean for LSR and full fairings.

Does it clear 2" oil pans? By the look in the photo it doesn't seem like it would.

He also appears to do a sidewinder on his website but no individual price just a package price.

Who has used his systems in drag racing vs Brock sidewinders and how does it compare?

At the moment im biased to a brock system as they are proven and used in Australia. Have only seen vance & hines in oz to compare.

[glenn71]

it would be interesting to see a torque curve printout of the insidewinder 4 into 1 versus say a brock 4 into 2 into 1 pipe to see the average torque values.Average numbers beat peak numbers.

.....and, with any luck, it's all in the headers.
Would be good if it had a nice long exhaust stack like the Brocks/Hindle Streetsmart 3 System.
They would sell a lot better as would not attract attention from our Highway Patrol Officers.
Ozzie coppers don't like short exhaust stacks

I copied and paste this from another site.. I don't work for Carpenter i'm just a client.. Call Carpenter for any questions regarding this pipe..

Anybody using this ?

[1vapors]

Anybody using this ?

can't you read they said next Feb.

[speedduck]

No, i can`t, i live in some wacky country amongst reindeers.
I thought february comes after january, when this thread was started, this year.

Heyyyy.

I live in a far away country with reindeers ......

Don´t steal my mojo.....

I have heard about that film but havent seen it yet.
Love the Ockelbo

BTW I live in ALTA. 200km north of Hetta in the far north of FInland

[speedduck]

Ookay, i thought that Yngve must be some Scandinavian. Is there lots of busariders in that area ? I have visited couple times Mo i Rana motor raceway when driving that direction, there seems to be some bikes, they were having some practise sessions.
And what do you think, there was some time ago in Rovaniemi "World´s Northernmost Power Shootout for Bikes" as it was advertised, just under arctic circle, would that be exact ? I thought maybe in Canada or Alaska would have their own happenings, or even in Siberia, nobody knows what happens there 

So, do you know anything about Carpenters insidewinder ? 

[Yngve]

When Hayabusa was released in 99 the Norwegian importer ordered 50. 11 of those came to my small town !!!!!!! ( we are around 18000 here ). I have been at ACR many times the last few years. Even riding my Busa on the track. I have also been to Kemora and Virtasalmi ( Motopark ) in Finland with my Hayabusa.
A friend of mine owns a dyno in Alta so we have the worlds northenmost power shootout every week ( I live further north than any mainland Alaska or Canada that has Bikes on the road ).

Don't know anything about the Carpenter other than I heard a rumor that it was "delayed".  Maybye Knecum can say anything about it ?

[BUSABOYSA]

I asked Steve, and he said they will not be making them. Pity, from what i have seen they look quite nice.

Thank you for solving out this matter. I thought also it would be just what i was looking for. Now have to find some big exhaust which goes under motor. I had HMF big bird before, it was ok.

i am not trying to bash Carpenter in any way. Has anyone bought one of his packages and seen the same or real close to the hp numbers he is posting on his sight that.

My guess is that it depends on what standard you are using measuring power. Dynojet`s own STD might be most optimistic, SAE gives less and, what we use here, DIN gives even less. Just take the bike to LSR event and see what numbers comes up. Karl had Carpenter engine package and i think it was pretty fast.

[entropy]

what do i (Karl) say about Bob Carpenter?
Simply that going to his NA 1635 kit was unequivocally the best decision i've made in LSR.
period.
FULL STOP (for those geezers old enough to remember telexes)

My Johnny Cheese dyno numbers fell well short of Bob's numbers; did i care?
nope.

I built a Carpenter 1635 in mid 2010 and started running high 2-teens, me 240# suited, 6' 3"
did some tweaking & technique improvement...

Greenie (asphalt bike):
March 2012, I ran 224 at Texas Mile in neutral air, next day i went down HARD, started having friends ride my bikes.
then...
Colt hit 203 in Houston 1/2 mile
Zack Millholland (smaller guy) ran 227.3 at Wilmington Mile, neutral air
Colt (smaller guy) ran 230.1 (twice) at Loring Mile, lil tail wind at start.
Colt hit 208 in Loring 1/2 mile!!!!!!!!  Holy schittttttttt!!!!!!

RustBucket (salt bike):
2 weeks ago Bob Sellers (big guy) set new MPS/F-1650 record = 225 at World Of Speed (record was 221), and no we weren't spraying.
Gotta say, this was Bob's 1st time putting tires on salt, 1st time he threw a leg over a 285hp NA motor bike.
1st full pass = 220.5
2nd full pass = 224 (qualifier)
3rd full pass = 226
all with 3-4mph side wind, no help from mother nature.
there was assuredly more in it as Bob's technique markedly improved each pass, but in impound Ryan made me an offer...

Fancy custom streamlined plastic?  nope, off the shelf Catalyst, no mods to it.

Best part?  = longevity!
Nov 2010, I pulled down the motor with new pistons & bearings ready for replacement.
Didn't install em.
head perfect, leakdown 1-2%

Sept 2012 I still have those 85mm pistons & bearings on the shelf.  Anyone wanna buy em?
I am out of the game bc of injuries, but Ryan O. has RBR and Dean S. has Greenie so i expect more great results.

Why did i take the time to tap all this stuff?

Because the advice of Larry Forstall, Steve Knecum, Ryan Ostergard, Bill Warner, Fred Vance, Tom Gates to go to a Carpenter 1635 kit was, like i said above, the single best decision i made in LSR.

How do they hold up on the street? Can you get 3-4,000 miles on the street out of them? When you say high teens, do you mean 8 teens?

[fvance]

Every one I know,3, that has the "new" Carpenter 1635 head is close to or exceeds Carpenters claimed 290+hp. I have two "small blocks", 1350 and 1340 rhey both make around 235hp.

[RansomT]

I assume he is talking 218, 219 etc ....

[entropy]

217-219 in the mile.

hold up on the street????????

That is NOT a street motor, 18.5:1 CR.  gotta use race fuel.

Do you know what dyno was used with those engines ?
I`d love to see that head, don`t have the money to buy one, spent all in mine, and it has to do.

For Winkelman, you have to take down few 10hp`s to make it streetable, i have that kind of engine and it took awhile to find right compromise between power and longevity.

[fvance]

Both Karl's motors and both mine were on Johnny Cheese Dynojet Dyno. The last time Karl and I were on JC's Dyno( same day), it was 85-90 deg, fairly high humdiddty, 1000ft elevation.

[j winkelman]

I was thinking of the stroke lasting on the street. Mine is just a 1397 and makes 215hp. I would like to stroke it if I new it would have the longevity and dependable as my motor now has. A couple 1,000 or so miles a year.

[entropy]

i think a 1635 would easily last 3000 mi on the street, especially if you were judicious about often you took it to the limiter...

I'd hate to lower the CR to the point it could take 93 octane.

If i were gonna run a $15,000 motor on the street, i'd pony up for 20 pails of Q-16 (100gal = $1400)  and keep the Cr at 18.5:1

[j winkelman]

I dont mind puting c16 in it ( i do now, mine is 14:1) My idea of a street motor is c-16 fuel but going on 150 mile rides and a little street racing now and then. The big thing is lasting more than 3,000 miles without taking out the bearings

[entropy]

Q-16 makes more hp than C-16 in my very hi CR motors.

i don't think the Q-16 costs much more...

[RansomT]

i don't think the Q-16 costs much more...

My purchase price for the shop as of this past Friday was $82 a pail for C-16 and $110 for Q-16.

[knecum]

The thing you must worry about on the street is oil temp.. I wouldn't run this as a daily street driver, with that comp..your just asking for trouble.. now if you want to blast up the street thats fine.. but ride it as street bike..idk i wouldn't.. unless you don't give a shit whats going on inside....imo

[entropy]

weird on such high prices!

In Houston, i pay right at $70/5gal of Q-16; bring my own Jerry can, they fill from a 50gal drum.

BTW:  VP guy told me don't store Q-16 in a plastic container and don't store it for any length of time in the 5gal VP pails.
use a metal container with a solid O-ring seal

I believe that is has to do with what the state and local laws are on MTBE and lead. Some states can't sell fuels with MTBE from open containers and some can't sell it at all.

I totally believe that. I have kept oil temp under 200F, at that point it needs more than hi-vol gear to keep pressure up, it can`t drop under 30psi if wanna keep big stroker alive. Of course idling takes it down with warm engine. Over 2500rpm it`s around 45-100psi.

[glenn71]

its interesting that someone has put an rpm and oil
pressure minimum number attached to a stroker.my thoughts on oil pressure
at idle were pointed towards the camshaft and buckets,as low oil pressure thats restricted
into the head with stronger valve springs and more aggressive
camshafts means more wear potential.With the crank and rod
bearings i question how they would wear much under almost no load
with a closed throttle,do you think the high  comp is too high
relative to the given oil pressure at idle?

[speedduck]

You can have 400hp turbo engine with lots of torque and still high comp stroker n/a will wear bearings easier. I have found that there is lot less trouble when put in a hi-vol oil pump. I have standard oil filter and must be careful with cold oil, not to spray oil allover before it warms up, after that it`s ok and holds up pressure. Now the bike is very streetable and can make longer trips with a passenger. With NOS you can make few pulls and that`s it, i can put the 240rwhp on the road anytime.

[speedduck]

Yes, that`s true, cams will wear if there is not enough lubrication. This one time i had some trouble with AFR and there was very high temps, lost exhaust valves and little damage to head, there was also exhaust cam and buckets started to wear, oil was too thin at that temp in head. Now there is quite blunt nose in cams and spring pressure just enough it works.
(what was the question again, little ADHD going on)
