Red shift 511 vs HQ-0034

[Dime]

Trying to decide between these two cams for my 2001 electra glide 88 ci. Both apparently do well in 88 ci or 95 ci.

I am looking for cams that pull all over the rpm range. Was talking to reps for both companies and they said power band is off idel to 6000 rpm.

Here is the specs for both cams. Which do you think has the better setup? Still trying to wrap my head around cam specs.

Price wise the headquarters cams are about $200 cheaper so if the performance is not going to be that different i will go this way.

Thank you,
Dime

For different reasons I would not use either and would go to a Andrews 26. Early chain drive and lack of adequate valve springs limits choices.

What would be the different reasons for choosing  the tw26? I have read the HQ-0034 out performs the tw26. There is not a lot of feedback on the red shift 511 so far.

No cam will pull to 6000 on 88tc in a bagger with stock comp. Didn't do it in my carbed fxd.

That makes sense.

Here's a 0034 in a stock 88" engine, V&H Longshots, SE AC, CV40 carb

That doesn't look terrible considering the Longshots.

He rode it for 12 years like that, traded it in for a M8 Street Glide.

One more suggestion SE204

That don't look too bad at all. Thank you.

My only concern with the 204's is every thing I have read says the 204's need the big bore or more compression to run well. I will be avoiding a 95" build for as long as posible

Its a 236 / 240  cam that is a little hot rod cam in the 88 and transitions to more of a torque grind at 95". You are in Canada, use the HQ it will save in shipping and duty. The heads are a constraint even at 88". They have no added flow after .400 lift and have a terrible restricted dog leg exhaust port. The small added exhaust duration and close LSA of the 204 will work well and the HQ-0034, 236/250, would act the same but come on later as a bolt in 88 cam.

Ya the head for sure totally get you there. Man if I was made of money I would have some engine, LOL. I am not however so i just got to piece this puzzle together one bit at a time.

I much appreciate your advice and ya the HQ-0034 is looking good. Thank you

I run the RS511 in my '02 FXD at 88". No dyno numbers, but runs great. More power off the bottom & pulls hard. Mileage dipped from 52mpg to 48mph, but that's likely due to me twisting its tail more. Valve train is dead quiet. FYI- Cycle Shack slip ons, free-flowing a/c & rejet/carb tune. I'd been planning on going to 95" the winter after I put the cams in, but it runs so well that I haven't felt compelled to mess with it.

I am still not 100% weither I will go with the HQ-0034 or the red shift 511. The reality is the red shifts will cost me well over $600 Cad. The HQ-0034 list price is $322. Both are very similar cams though I think I like the cam specs on the red shifts more.

That's a chunk of change & I totally get that. I rolled the dice & went with the RS cams & couldn't be happier. Bike starts easier & just runs like it should have from the factory. I remember looking at the HQ34s & being interested in them, when I was researching the cam question & don't remember why I didn't go that route. Then, right when I was ready to finally do cams & leaning toward SE204s, Zipper's released the 511s & they just seemed to make perfect sense for my purposes.

If you search the Dyno section, Zipper's posted sheets with RS511s in the same '05 FLHR at both 88" & 95".

I tried the HQ-0034 way back when it was the cam of the month.Since I lived in a mountainous area, I found it did not have any deceleration engine breaking I needed when going down into a turn. I had to use a lot more brake. Other than that they seemed to be an ok all around cam.
