Street Glide 100 hp/100 torque

I'm planning on some engine mods for a new Street Glide. The dealer is recommending the 29775-02B Stage 2 with the SE203 cams. I've told him that I'm looking for the miracle 100 / 100 and he said I'll never come close with just Stage II and SE203 cams. I'll have a set of Vance & Hines pipes and a PowerCommander USB on also.

Any suggestions on what would be a better build? I plan to have the work done before I even pick up the bike.

Regards,

Matthew

Well 100/100 would be nice but really I would think tuned, good pipes, 75-80 range hp and 85- 88 range tq.

You will need ported heads a better cam to get those levels. It is not hard really a set of ported heads, 37 cam will get you there. You 100 hp mark is something that is more for show than go look hard at TQ levels that is " fun factor" check out some dyno sheets and go from there.


One thing that will give varied results i cc chmaber volume on the stock heads. Larger chamber are going to result in lower compression ratio and that will end up producing lower numbers. You may get luck and have a set of heads that are in the correct range. Use of a .030 head gasket will help you bump your compression and get you into the 9.3 range on avg and that will help you out some. I would choose the 204 cam over the 203 as well they tend to produce better numbers. Good luck with your new build

True on the hp, but for distance highway runs I'm going to need the hp to maintain a higher than normal pace.

What do you think about ported heads and say the 204 cams.

I'm also thinking of gear and not chain cam timing based on what the dealer said. Even though I'm not sure why.

Many are happy with the tradiional Hippo build (570s & SE perf heads all bolt in) or 37s and ported milled heads 95", Wood tw6g cams and just cleaned up and milled heads, ccd, would work too. be conservative on compression, gas is not getting any better and this is a bagger. If loaded as many do on long hauls we want to keep the stress and heat down.

Dewey's Heads

Dewey's Heads and a 37G cam will get you exactly what you want and then some on a 95 incher. Check his reputation on this board and Harley tech Talk. You get what you pay for.....

Matthew, I am right there with the S&S super sidewinder kit, which comes with 585 cams, gear drive, adj. pushrods, 79cc heads etc. I also added 95" kit, using S&S pistons, the Rinehart true duals, and a PC111usb. Bike is easy to start w/o comp releases (10.3-1cr) runs great, sounds amazing, and delivers excellent fuel economy too! I am now waiting for the larger intake manifold, that will help too!

99hp and 103tq

The build already had 14k miles on it last week when I did my first dyno run. Only tuning it had ever seen was me using the HSR and HQ guides. Dr. Dyno just ran it 3 times and printed out the sheet.

99hp and 103 tq

SnS 570G with SBC Vortec heads (close to SE) at 9.8:1. Rev limit set at 5900 and still climbing. Using e-series (14 plates) on FLSTC

Great solution for a cheap but rock solid build -SE heads and 570G and you will get 100/100

If you plan to stay with Screaming Eagle...the 204 cam is a good choice on a bagger..

88hp 88tq

I just finished a 95" stage 2 build but opted for 211 cams and s/e race tuner. The race tuner helped get a great tq and hp curve (no dips) but you will definatly need head work to acheive those numbers.


06 EG
95"
211 cams
SE A/C
SE race tuner
SE plugs and wires
D&D fatcat/ perf baffle

When I had my 95" dynoed the guy before me had a 95" with 211's, PC and stock heads and his numbers were closer to 80. He expected much more and was not very happy. IIRC there was no hd map for those cams with stock heads, so my guess is that hd must of assumed that anyone using that cam would also do the heads.

My dealer did haft to wait on some place to order (e-mail) them the map for the set up I had done, I do not know were from. They said it was for the fat cat exhaust. They quoted me 90 hp before the build. It did not reach that but the dyno chart after they tuned it was real good. Nice tq. curve from 2400 to 5600 rpms (81-88-81). Hp. staight from 1900 to 5900 rpms (26-88).

Agree above comments that you gotta do the heads to get to 100 ft. lbs. I squeezed 95 ft. lbs. and 83 hp. out of a basic 95" and SE203s with V&H BSS and a PCIII. But to get over that hump I would have ported and decked the heads to get into the 9.8:1 compression range. H*ll, it's almost not worth getting into the motor if yer not going to clean up the heads. I'll just never learn.
