My brother wants to put new cams in his stock 88 ci 2005 Springer. He usually rides two up but wants a little more all around power. A pc3, air filter kit and exhaust is already on. He has 20k on the motor and doesn't want to break the motor down yet and wants to do cams only. I am thinking Andrews 26 or 37 cams. What are some of your opinions on these two cams? Something different I should look at?

 

Tech & Mech Forum > Engine topics...you'll get a better response

 

As mentioned, take a look around the engine forum, there is a TON of cam info there. Any advice from Scott at Hillside, Kirby at Pro Drag or DJL is good advice as this is what they do. There are a lot of cams that will fit without having to open up the motor and if you use Quickee push rods you won't even have to take the rocker boxes off...

 

Ok. I'll try to navigate there. Using my phone...

 

I have the SE211 in 02 with the 88. Lots of torque!

 

I studied cams for several weeks back in 08 and picked the 26h's..

They are easy on the engine, cooled my oil temp by 10-15 *, increased my mileage 2-4 and most of all they netted me 15-20 lbs of TQ all the way across the sheet..

Great cams for riding two up.. which we do as the wife is on the rear 90% of the time.

7yrs and 40k miles later, I'd do them again..

Here's my original dyno sheet before the cams, but with the SE/AC and pipes added prior to the tune.. its a Baseline run to see the difference after all work was done..

stock base run was - 78 TQ and 63 HP

Heres the dyno results after the 26h's put in and dyno tuned...

after cams -- 92 TQ and 80 HP

I'll add the SE211's are strong cams,, but you'll need to bump up the compression of your head and/or even better do some head work and they will shine. Or if you ride about 3k rpms all the time they'll be OK.
.
If nothing is done the the top end then they are not the best pick for 2 up riding if you ride in the 2K to 3K rpm's range. If so they don't make as much TQ down low which is where most of us ride a lot as a lot of other cams will..

After thinking a bit more. The Andrews 21's would also be a good pick... the have a little more lift than the 26's and they move the TQ line to the left on the sheet.

Meaning the TQ falls off a little faster in the high rpms. But that also means they come on a tiny bit earlier that the 26's... somewhere around 200-300 rpms difference in the two cams... Which in real life, you'd Barely notice the difference in normal riding..

bottom line either one would be good easy cams if you spend a lot of time in the 2000 -3000 rpms range....

most of our riding is in the 1800-2500 RPM range - and has been for 9 yrs and 53k miles..

I agree, I like the specs of the 21's... I just installed 37's in my Breakouts' 103 and love them, but wouldn't use them in a stock 88, they need more compression.

 

As it's been said, the Andrews 21 is a great bolt in cam for the 88" engine.

If he plans on going to more displacement, the Andrews 26 is a great choice for a 95" engine.

How many miles are on his bike? If he's doing cams, and doing them himself, he can invest some of the money he saves on labor into upgrading the cam chest parts - new support plate, hydraulic tensioners, new oil pump.

If he does upgrade those parts, he'll need conversion cams. Andrews also makes conversion cams in the 21 and 26. Just some food for thought.

 

20k on the bike. I'll be doing the work and we plan on getting new chain adjusters and lifters. I think he is liking the 26 cam but he refuses to open the motor up to increase the ci's just yet.
