Who builds the fastest Q-jet
 

I hope this doesnt cause a huge argument, but I am curious as to who builds the fastest Q-Jet carbs out there.

Thanks

Re: Who builds the fastest Q-jet
 

There are several really good builders, Danny Ashley, Dean Oliver, etc., but I don't think there's a truly bolt-on and go-fast carburetor. I think half the battle is getting it jetted correctly and having the air valve set "perfectly". If you could afford a Racepack with O2's on every single cylinder, that would surely help. If you can't, count on lots and lots of track testing. My .02.

I have had both Danny Ashley and a Dean Oliver q-jets. I would say they were both very close to the same. Ended up running the Danny Ashley carb all the time based on the back-to-back we did. Actually had Danny Ashley go through the Dean Oliver carb I had because I liked the changes he made to the Q-jet. Sold off all of my SS stuff last year and the guys who bought my Danny Ashley carbs actually called and ordered more from him.

Having said the above, both guys are incredible to deal with and are as honest as they come.

How do you get in touch with either of these fellas ?

Danny Ashley 765 647 5102

Dean Oliver you can google Deano q-jets

Alot of times there are good ones on this site for sale. I bought one that was race prepped by another builder and it worked fantastic for $500.

I think the guy that knows how to take his Q-Jet, T-Quad, Holley or any other carb and adjust it for conditions while at the track has the fastest carb.
I've watched guys not touch their $500+ carb because only the zen master is allowed to change jets, metering rods or any other re-calibration. I think any one of the guys mentioned offers a great product but if a dunce is operating the car, nothing can be said about the carb.

There ya go.

Re: Who builds the fastest Q-jet
 

I use Ashley and he is great to work with. But one thing to keep in mind is that with most carbs, what you start with directly impacts what you end up with. There are good cores and not so good cores. The builders listed above are great at enhancing a q-jet for performance. But if you have a bad carb, not much can be done to make it perform like a good carb. From what I've been told, it's all about the top, not the body or base plate.

WOW Q-Jets....

I have a Bobby Warren and WA Lee Carbs

Sent the Warren Carb to Val Headworth...
It got the royal blueprint treatment with new air bleeds, and internal components.
I know it works well Budd Rowe borrowed it for a buddies 74 Nova.

Still trying to get my 69 Impala out of the Resto Shop.
Hopefully the year will generate enough money to get it finished.

Re: Who builds the fastest Q-jet
 

I used to do Q-Jets also but as I am really a MoPar guy I decided to concentrate on the Carter TQ as there were very limited builder outlets for racers.That said, I have seen examples of most of the "good" Q-Jet builders out there and I have to say I would lean towards Ashley for the Stock/ Super Stock combos in general. I have seen several back to back tests and his seem to come out on the winning end. Danny's drivability, in my opinion, is better. Once again this is just my opinion, for what it's worth. Jim

I don't use a carb, but have worked with Dean Oliver on some data logging and wide band O2 projects and I sure am impressed with his knowledge. Nice guy too.

Re: Who builds the fastest Q-jet
 

All of the builders mentioned do great work , but when its all said and done its all about the CORE.

Re: Who builds the fastest Q-jet
 

This is probably the most intuitive statement so far in this thread! You can't make a silk purse out of a sow's ear! Jim:rolleyes:

Re: Who builds the fastest Q-jet
 

The core is the big piece to the puzzle. Once you have a good core the the above mentioned racers make them great. In addition, I have used Jim Boburka and Gary Stinnett carbs with little to no variance in et and mph.

FWIW

Re: Who builds the fastest Q-jet
 

I spoke with Danny Ashley this morning and I gotta say, he is one super nice guy. I appreciate all the info from everyone. Thanks

Re: Who builds the fastest Q-jet
 

When you all say" its all about the Q-jet core" . What do you all look for? So one might know what core to send to one of the Q-jet builders. ThankYou Kenney Kelley

Re: Who builds the fastest Q-jet
 

In saying its all about the core that does not mean a SPECIFIC # core, it means its all about the core in general. Those of us who have been using these carbs for along time know that it could take as many as a dozen or more cores to find one that really stands out. Now that being said I don't expect someone today to go out and try a dozen carbs, I was just stating a known fact that took 45 yrs or more to find out. Guys like Danny and Deano will put you in the right direction.

I show his number to be 765-674-5102.

Re: Who builds the fastest Q-jet
 

Hi To all, I am very new to this forum,but not new to NHRA stock class
racing. I held a few records back around 1975 in F/S . This forum is
such a great place to learn. Back in my day,the only way we shared info
was at the races or if you got to be a trusted buddy of someone,you may be able to call him and talk on the phone for a few minutes,but that was about it. Anyway I have always been interested in carburetors,especially Q-jets ,because in 1975 very few people knew
how to best modify them for competition. Anyway,what would you think
would be the difference in et between a really good Q jet and one that
was just average. I know there is not an exact answer,but because of
reading this thread I began to wonder how much faster a really good one was compared to one that was not built with a good main body or top? thanks ed

Re: Who builds the fastest Q-jet
 

And stands behind his product, another racer had an issue with a bog on the two step, and I had mentioned I was going to be using a two step, and the next thing I know he sent out the suspected problem part with a modification on it. Granted I didnt need it so he asked to send it back and he would cover shipping costs.....no money out of my pocket. He also emailed me a tuning guide which is mind blowing how in depth it is. Lets not forget that his q-jet on my combo compared with a known working carb was equal or better on the dyno and in the car. Worth every penny I spent.

Re: Who builds the fastest Q-jet
 

Re/ the issue of differences between carb cores- I had two carbs done five years back with identical jetting, hangers, rods by another "name" builder.
On the dyno, one made 6 hp more than the other on back to back pulls.
This year, I've sent a carb to Danny Ashley for updating and the latest improvements. Danny was great to deal with, spent time going over every detail on the phone and has a tremendous base of knowledge. He has a test engine he can setup the carb on to confirm idle speed, etc When the carb came back I didn't recognize it, looked like a new carb! Instructions and info on setup were supplied, even a spare rod clip and hanger screw! You could not ask for a nicer guy or for better service!
I'll be dyno testing it next month , but for sure expect the new carb will be easier to drive and use less fuel in the pits/return road as the old carb had all four barrels opening together, not progessive, and was easily loading up driving under light throttle except on the track. With the old carb, I had to complete my burnout to clean up the motor before a run....

Re: Who builds the fastest Q-jet
 

I for one would be interested to hear if the new changes netted any
more horsepower and torque . Also like you said, did the changes improve the driveability . ed
