Title: "Starter" for a Blower
Post by: bud on February 10, 2013, 03:14:40 PM
Anyone ever built a snout started for a 671 root blower.

No, I have been advised to use the starter that I have. I purchased a belt guard with the ability to be used for a bl;ower starter, and I have received advise that as lon as I have that I should put the dog on the pulley should I have a problem with the current starter. I would like to see a home built starter.

It is stripped, I do not know what with, I want it to be loose as the engine it is on right now was never ment to be a blower engine.
I will be 20% under driven, I just need 3 tenths. It is a high velix modified retro stripped 871 blower.

This engine was not built to take that. It is the completely wrong set up. I was running 8.59 in the 1/4 last year and want to be able to run an 8.5 index this year.

By adding just a little boost it is a 101 class on running a blower and I should have enough to tune to that 8.5 index.

I'm not one of the big boys yet, but working on it.

Glenn - I'm thinking a little in your direction, no blower though, just want a little "boost."  Gonna try some nitro this year and see if I can fine tune to a troublefree 9.60 index.  Slow but steady.......  here's picture.  I enjoyed reading the 6 articles you posted yesterday, helpful concise info from Spud.

xxxx Bud,how big is your engine? With an old worn out stocko non stripped 671 at 9.5 over was making 16lbs at 6k on a 350 cid deal.

Glenn
is your blower teflon ? and how much boost are you planning on ? How much overdrive ?  I'm running 33% overdrive with 12 lbs Boost with a 671 street blower but if I were Teflon I could back down the overdrive which I may do anyhow because I pulled the D cups out and put in flat tops because at 7500 rpm on the motor I'm spinning the Blower close to 9000 rpm and I still end up pulling the blower and replacing the bearing often and seals. So anyway I get a lot of Blower time on the bench.There are a lot of Differnt ways of going at this and for the last 10 years this was the easyest for me. I hate to Teflon concidering how long it last, 2 or 3 run and it's done.

Glenn...
I think you may be in for a surprise. The engine in my FED is only 365 cu. in. with a non-teflon
6-71 on alky. With about 11: 1 CR & 16.5% underdrive, we still struggle to slow the car down
for 7.60 index racing. Boost gauge shows about 11 lbs.
Your engine should respond real well to that 8-71. You may have to up-grade your licence...which is a
good thing  ;D

Upgrading my licence would be a very good thing. I want to go way faster!

Glenn, I'm getting a good chuckle out of reading this thread :P. I think you're in for a surprise, a big surprise.  I can see you grinning and shaking your head as you look at your time slips, saying where the heck did that come from.  Then you start taking timing out and adding fuel and the s.o.b. just wants to go faster. Or maybe you'll find out your tires are just too big, the gear ratio is too high, or something that is making the front end tend to stay in the air. Nitrous is a gas but being blown is better!  ;D

Sorry, I got sidetracked from the original question that started the thread..... I used to have a homemade blower starter, a heavy barstard, sold it and went to an onboard starter for my 540 BBC (12.6-1 compression, Littlefield 14-71 compressor). After ruining a variety of top name flexplates and starter drives, I invested in a Mezeire 10 pitch flexplate and one of their starters, no problems since. I have been starting it off a start cart, with two 16 volt batteries, just using a small battery to run my electronics. Anyways, I prefer the onboard starter. Also, one less person needed on the starting line.  Whatever you do, good luck and be safe.
