to dyno or not

[RatFink]

Yes, if it is a load bearing dyno.

So there are 2 types or more? That would make a difference in your results then, correct? hmmm... Don't get it?

 

[Sam Colalillo]

Here is my advice. I say take it to the dyno, if you want to go faster in the future. Don't take it if you are going just to get a number. It will be a good experience for you. You can ask questions all day long on this board but the learning experience you will gain from you actually doing it will be valuable to you in the future. You will get opinions all day long on this board. Some of it will be valuable, some of it won’t be, some of it will be guys who don’t make the power you do telling you how to go faster, some of it will be from guys who think they know everything, some of it will be mis-communicated from people telling what they have learned from a friend, some of it will be from people that claim to make power but have not actually done it themselves, and some of it will be good solid advice on how to make more power.

Here is my point. We all started somewhere and most of us don’t know everything. My first trip to the dyno was about 6 years ago which resulted in disappointing me with 457 horsepower (my goal was 500). My knowledge at that time of these cars was very low, but at least I planted the seed of knowledge growth. Even though that trip to the dyno resulted in disappointment, I consider it a good learning experience today.

One of the many things Cal Hartline has taught me is to always lay down a baseline on the first pull. I strongly agree with this theory. Go to the dyno with a couple of ideas on things you want to try. Then follow through with them. The memory of your cars first time on the dyno will be engraved in your memory forever. Like anything else the more you do something the more prepared you are the next time you do it. This is why I say “Go for it and have fun”.

My first time lead toward making me more prepared for the future trips to the dyno. Now I do two things before going to the dyno. One, I make a list of things I want to test. Two, I call Cal and ask him to be ready for me to call him with questions.

Good luck to you! Just remember a 625 horse supra, a 650 horse supra, and 700 horse supra all have one thing in common…….LOL.

Dynamometer - Wikipedia, the free encyclopedia

 

[we4v6]

gnbrett is right there is a calculation i found on google... cant remember exactly what it was called but you can type in your 60 ft 1/8 mile time and mph and im pretty sure it asks for 1/4 mile time and mph .. it was with in 1 hp of what my pro charged ta made on the dyno... oh yea it asks for the full weight of your car also... cool calculator ...

 

[Grumpy]

It is what it is and no matter what someone says their "Can" do it don't mean chit till they go to the track. The track is not misleading, dyno's can be.

I love to watch guys that put down 5/600 hp on a dyno and race it at the track .. Of course they tell ya this thing is goin to fly as they rip off a 12 sec run @ 110 mph

Thats because the car may have 600 HP but its the first track day so they cant launch & they dont have the Patience to tune over & over like most here including me lately.

I can give anyone here a single pass in a 6000 HP Funny Car but lets see you launch it & run the number. One in 1,000,000 people if that?? I know I couldn't! Doubt anyone here could? Thats the Time & patience aspect of racing & some just dont have one or either of them.

The dyno is no more than a tuning tool IMO. It can be very useful but real life track experience is invaluable. Just go & watch 5 guys their first track day, it's funny at times the things they do & forget to do.

 

[Rell87]

I think you should take the car to the dyno if you are curious about the number... I did. But I was told its better to tune our cars at the track so thats where we tune my car.

Especially the Vette and Supra owners

 

[TIMS87GN]

Cal tuned mine on a dyno in BG. It was my first time and I learned a lot from it. I wouldn't trade the experience for anything. Like previously stated, it plants the seed for future mods. Our club got dyno time later in the year just for fun. Some guys tuned a little, but most just wanted to know what they were actually putting down. Everyone, including the disappointed ones, all said they had a blast and would do it again. Its fun and useful too.

 

[we4v6]

i had my procharged trans am dyno tuned it made 659 at the wheels and ran the best time of 10.94 @135 no 60 ft but crazy mph... im going to dyno my we4 in a few weeks i hope.. friend of mine owns rpmtransmissions and they just got their dyno working so i want to dyno it before i put heads cam and bigger turbo on ....

 

[bison]

Dynos are great for making improvements on a given car. Excellen tools for an expert tuner. I always had good results on dynos

 

[it's just a six]

I used this dyno on my Syclone. Dynapack Chassis Dynamometers
386 HP 550 ft lbs torque 21 psi boost pressure. 100% stock longblock.
Truck is really mostly stock.

 

[Scott89TTA]

my car dynoed 380 hp & 390 ft lb torque 21-22 psi but ran 11.55 @ 116 then turned up the boost a couple, locked the converter and ran 11.18 @ 119.7 and 11.22 @ 120.3 mph...that calculates to nearly 500 whp

TCI - TECHNICAL INFORMATION: Racing Calculators

great for tuning no so great for numbers sometimes...Dynojet's typically will produce higher numbers then a Mustang dyno...some say the Mustang is more accurate. I have heard the Dynojet's referred to as Dreamjet, Fantacyjet, etc. since their numbers tend to be a little on the high side. Mustang adds resistance & drag by way of Edie electric motors and Dynojet is simply a drum that you spin...calculates the weight and movement generated by the car into HP/Torque. Once you get the drum spinning real good it doesn't take much to keep it spinning and it doesn't change with wind resistance and drag that you get on the track...Mustang tries to simulate this. Some Dyno's have 1/8 & 1/4 mile features where you simulate a pass...this can be pretty cool but is kind of scary too.

Dyno days are fun and can be pretty cheap if you get a good group together...usually $40-$50 for 3 pulls. Get it done but don't be discouraged by the numbers. Get the car weighed with you in it and make some passes then run the calculator for a more realistic HP number.

 

[gnsrule]

Theres 3 different types of dynos. The first is an engine dyno. It will give you real world numbers on what the engine is putting out. The second is a chassie dyno. It will you give you a number on whats going to the wheels. The third is the most important kind of dyno I know of. It will give you a real world experience on whats really going on and the most fun too. Its the BUTT dyno. The first 2 give you bragging rights and the last gives the best. A big 'ol woodie

Have fun w/ whatever you do

I'll take you up on that. Nomex firesuit in hand. Might not run it's full potential but it sure would be fun.

Have fun

Haha, I love to hear guys in the pits or at cruise nights. Oh it dyno'd bla bla bla. Gonna run 10s. Most don't do squat. I just keep my mouth shut.:wink:

I am absolutly no expert on dynos but I would suspect an engine dyno would be the best or most accurate way to get a truthful number.

I have seen 2 cars go boom on a dyno. I guess if I'm going to go boom, I'd rather it happen at the track, kind of a war wound mentality.

 

[HighPSI]

If they went boom on the dyno, they were probably gong to do it at the track. The dyno is a little easier on body parts since you aren't going 100+ mph when it happens.
