So its been a while now since a lot of people have switched to baby/big blowers. I wanted to hear from these guys on how they feel the blower combo is performing for them. Consistency issues? Reliability issues?

Thanks

Back when I ran a 8/71 on a 540 with the Rons setup, at 9psi it was deadly. Of course i sucked most of the time but it worked very well

I have only put about 100 passes on mine so far, and i dont see any disadvantage. Car is as good or better than it ever was, and oil changes and checking valves just like normal is the only thing ive done.

Look guys i am trying to behave. Long time blower guy. Trying to run mild combo. Then here come a bunch of you running blowers. I have everything to run blower except the blower and lower over drive combo of pulleys. I could run 45 to 68% over easy enough.LOL

Question. What size pump are you running with these low boost numbers?

Chris Wilson put together a 588 headhunter deal with a 250 on it for me last winter. This thing is incredible. I'm right at 200 passes so far. Check the valves and change the oil. No issues what so ever. Its stupid fast for what it is. I was going 4.38 @ 160 at galot last weekend with 8 degrees of timing out at the hit and 5 psi boost. Amazingly consistent. It's an awesome deal. Chris really has these things figured out. I wish I would have got one sooner. Call Wilson race engines and get him to fix ya up. Best in the business. You won't regret it.

I am curious to know more about this, ET etc. Seems to me that the carb would be a big restriction on performance.

Bruce, these little 250 blowers are the hot ticket right now in bracket racing. Most are only set up for 3-5 lbs boost with a single carb. The low boost allows them to be bolted to a std bracket motor like 582 and 598ci engines with no mods. You can make a 4.60 dragster a Consistent 4.40 dragster for little cost.

I'm sure it could be if it were being pushed. But that isn't how they are using them. 5 psi is barely anything, and just picks up the easy hp at the bottom of the boost numbers.
I have found that going that direction would only work for me if I welded the pulleys on so I could never change them.

Any one know max od blower work efficiently at?

Highest boost they achieve? Boost is relative number depending on rest of combo understood. Just wondering how far blowers can be pushed?

What are you guys running these having to change converter wise?

FordRacer9326, i just ordered one of the TBS 250's with a 67 bottom and 33/35 top pulleys from Alkydigger. This one is going on a 13:1, 598, Dart 380 Pro 2 CNC head, 1025 hp NA, BBC with a enderle bird catcher. I'm trying to figure out what top pulley i should start with. I'm targeting 4.40's to 4.50's just like your combo. With the enderle bird catcher on a tunnel ram, 210 lb driver, and all the gear it goes in at 2000 lbs, so i'm figuring i'll be in the 2100 lb range with the blower and 10" converter.

What pulleys are you running on your 588?
What converter are you running?
How are you measuring that 5 psi?
