Questions for dynoman14?

[drtrkr244]

Since u are in Ga.,who would you recommend as a 604 crate rebuilder?I am assuming you are a tuner based on what ive read.Sorry if thats not true.

Should I start with a new one, or buy used and have it re-built?

What are the hp differences between the two?Ive been told new ones are all over the place.

[supercomet32]

some will agree some wont ....RACETEK....last place I picked mine and it was actuall 5 HP above what he claimed but then again not every dyno is the same....also dont buy into the bullshi t your about to hear from everyone about staying away from dynoman....just make sure you check your info and take things with a grain of salt. some people think he's a snake oil salesman but then again i bet they are getting beat listening to their snake oil saleman that works on their stuff. mans gotta eat so theyll all sell you what you buy into know yoru facts and buy accordingly and dont ever ddiscredit a man for stepping into the grey area or trying a new way of thinking

Im not buying into all the negative about dynoman.He definitely thinks outside the box, as well as I do.

His customers that post on here always have good things to say about him and his products.

My dad was personal friends with Smokey Yunick, and most people at that time didnt like him either., but look at everybody says about him now.

Ill be using some of his products, and Ill let you know my results.(unless there too good,and ill keep it to myself)

604 in GA

DRTTRK244,
I am not a certified builder but I do have my engines fully inspected before and during the build process by 2 Certified engine builders in GA.( Darrell Gabriel and Johnny Pruitt ). I will dyno the engines at their shops prior to leaving and once they are all good I get the seals put on them.

I am able to build engines for UMP and NE Mod without seals and build and re-build 10-15 of them per year.

I also build Outlaw Crates for the NE and Mid-West that have both pavement and dirt stock appearing style engines that use 100% Crate parts. These engines check legal in almost every aspect but stretch the rules in a couple areas and they are capable of 500+ HP with GM 604 parts. I have a couple road race customers that run very competitive in their series running against open engines weighing 300# more and their crates are close to 600hp, our only change is we are open on valve springs and we run my "Alien" branded 1.250" springs on those engines and turn them 7800. I can tell you from experience if you get off on timing 1-2* or get bad gas the 604 pistons turn to butter. We have since gone to a "Ti-Ceramide" coating that will withstand 40 degrees of timing and 20% lean without melting.

I knew Mr. Yunick pretty good as I got into a pretty well known argument with him at a PRI Show in Columbus OH, back when I ran Serdi Corp. It was related to rod length, piston speed as it relates to restrictor plate engines. The following year at Indy he came by, bought me a beer at the concession stand bar and told me that I was exactly right. I already knew that as we had 3 cars in the top five and five cars in the top 10 at Daytona ARCA Speed weeks, all the drivers we rental customers mostly late-model guys that had never been there before...

From that point on we were pretty tight. I hated to see him go. Since the late 90's I have tried to work on one of his ideas that GM purchased and locked away in the vaults. He was using "gas vapor" technology to get 1bout 100mpg and 500hp on a 350 chevy. I saw one of the old test engines at his garage and it had an old 1BBL Stromberg Casting on it with a top that screwed on from a welding tank. Anyway that was just one of the many things he did about 50 years before it was time, I always used to joke that he must have been born in one of them restricted areas like AREA54 or whatever it was called.

So if you want you can contact Joe & Bobby Dauderman, they won the Crate-V-Open engine race last year at BelleClaire with a Fastrak Legal 604 I built him. Yea it was slick and he was on the bottom but a win is a win, right.

As far as what I do different, well to start with I pre-select the best parts you can get. There is +/- 10 difference in heads, intakes, cams, carbs, waterpumps, ps systems, belt drives, distributors, headers, extensions, mufflers and the list goes on. If you maximize every part and confirm it via testing on the flow bench, engine dyno and chassis dyno, then you can have a piece that is +50HP better than you started with.

PM me and I'll let you know some of what I have found in the last couple weeks chassis dyno testing some new ideas on my engines for a couple top CUP drivers that also run crate late-models.

Nothing against Dynoman14 and his programs and I know they are in NC, but Hendrens is a certified Nesmith, Fastrack and GM crate engine rebuilder. They are upfront, very knowledgable and will do you right. We just got our "open" engine freshened, needed all new Titanium valves and a new aluminum ATI super dampner and he came in under the original quote plus the added parts by $600.

[drtrkr244]

Where is this at? Ive only ever seen one person claim to use his products and he claimed it didnt do what dynoman said, lol..

So since you say they are on here please copy paste Ill love to see all these good things said about him.

Its been a while, since i dont keep up with the crate stuff.

I have a family friend who has alot of dyno experience testing all kinds of hp motors. He says dynoman is working on the right areas of making power. At one time, he worked for Holley, designing and testing carbs for NHRA pro stockers. If he says dynomans right, then i know he is!

So with that in mind, Ill take my chances.

[drtrkr244]

Ok so just to be clear you havent seen any posts on here by his customers?? You posted that you had but now recant that statement?

Yes, i have but its been awhile.

Dynoman, your pm box is full.

We have been using dynoman's stuff for 4 years now and have always been very satisfied with his work! His carburetors are second to none...IMO.

We don't get on here and post about it very often for several reasons.
1. Just like any other racer, when we find something that works we don't run around the pits telling everyone so that they can do the same.
2. We don't want to get into a pi$$ing match with those that don't agree with his methods.
3.We don't post on any forum on any topic very often.....just not that into it.

We will just keep winning with dynoman and let others do what they wish!

Thanks Mark!

A smart racer never tells everything, he just points you in the right direction. Then its up to you, to figure the rest out!

I have a carb at his shop now. I have been dealing with him for two years. Everything he has EVER told or sold me has worked as advertised.

The reason you do not hear about it is we don't care if you like him or not.

How about shut up and race.

[dirty white boy]

but is it crate rule legal???

[supercomet32]

IF he's winning with it Id say yes its legal. If he's getting DQ'd Id say no...i fyour not pushinng the rule book your leaving something on the table. AND HE IS WINNING WITH IT

[Egoracing]

Lets compair apples to apples:
1. What are you running of Dynomans?
2. Are you turning the engine 7000+

Just because he is winning really means VERY little. We won limited AND open late model races with a straight form GM crate and we were not using ANYTHING that Dyno sells even though he posted that we were running it. When we won 2 of the 3 Nesmith races at Eastbay he posted on here that the winners at EastBay Crate Races were using his parts. Neither car that won that weekend was using ANYTHING he sells. Then his reply was that many crew members buy his parts and put them on the cars without the driver or car owner ever knowing!

[supercomet32]

I guess you didnt see a winning driver post tha the was using dyno's stuff...then someon easked was it legal...he has won numerous races im sure if it werent he wouldve gotten caught....like i tor not dyno's stuff is in use and it is in winning race cars...is it unorthodox sure is it in the great area sure but is it illegal? if it makes it through tech id say no its not illegal.

Yes I did, I asked what he was running and if he was turning the engine 7000+. Never asked a single thing about if it was legal. One person that has posted here that siad they were running the springs and oil said his engine would not hit 7000+rpm but floated the valves at about 6700 which is where stock valves fall off. ON one has claimed that they have hit the RPM OR power that Dyno is claiming.
If you do some research you can finr Dyno on other boards and even on E bay. His system is so good that he has bought several sets of used crate engine valve springs on E bay and "treated" them and resold them to others as Alien springs. I guess his process can restore worn out valve springs back to original, to bad Nascar knows nothing about it or they would just be re-using springs, also an easy way to make a much higher proffit also.
