DYNO DAY - Gauging Interest?

Just wondering how many people would be interested in a Dyno Session? I was thinking Early April. Time to get the ball rolling on some events :cool:

So if your interested post some dates that work for you.

im down for sure.

but i heard that harveys dyno isnt that accurate for ls1's or something:confused:
or it doesnt dyno ls1's properly.

i mite be down
i wanna see how much hp w/ the n20

ya jon ill be in for sure as well, want to see a base line before headers go in this summer

what's the difference between a Mustang Dyno and a Dynojet?
And why do they call it a Mustang dyno? :confused:

id be in :cool:

cuz ls1's make too much power:p


anywho i'd like to see if i can crack 400rwhp:D ...

but i'm not holding my breth:blah: :shame:

Which shop and how much$$$:think:

if its harveys and ive got my rims Im in . :bow:

i would go, that is if my car is in 1 piece.... we will see

Harvey's dyno can't get a proper RPM readout for LS1 guys & my car since I have LS1 coils now, if you can't get a proper rpm readout, the numbers you get are garbage.

It will be Harvey's Dyno, the problem previously has been LS1 cars with stock wires. I will contact Harvey on Monday and see if he has done anything to get around this problem. I do know that some guys who switched to aftermarket wires had no problems with the readings.

It will be at Resnick Racing and it will be $100 for 3 runs :)

the price is right..

but if what Matt says is true then i guess im out:(

i've seen LS1s dyno properly on his dyno .. i think only chriss had problems and a long time ago ...

the problem might've been the shortness in the LS1 wires (or so harvey said) .. if thats truely the case we can bring 1 long wire and swap it into #1 plug

but i've seen him dyno LS1s properly (i drove perry's myself on his dyno) and the rpm was reading properly

jd: tell him id be willing to help out this time as well ;)

I think I'll keep out of Harvey's way, Harvey is way too confident about his knowledge IMO, problem with LS1 he has was the multiplier was way off, trying to read my coils is a bit of a challange as me & 95wagon tried to hook up the wideband to read RPM on my car, but we got pretty close, we has to splice into the signal wire from the PCM, as we couldn't get any proper reading from the wires & mine are MSD & shorter then LS1's, I"m also not a fan of bringing a long wire which might be misfiring or who knows, I'd like to dyno as is, Harvey can fix his dyno & then I'll go.

I don't know if I'm letting you drive my car... ;)

Harv has had a hard time reading my car, with or w/o aftermarket wires. There have been some gaps in the readings and the rpms haven't been dead on, but I want to try again with him. Even with the problems, the numbers have been about where they should be. And, I think the last time he dyno'd me, the numbers were more consistent. Other LS1's have had better luck with Harv.

But I'd appreciate JD talking to Harv to find out the issue. I've spoken with at least 10 shops in the US (far away) about the difficulty of reading LS1's, and no one seems to have a clue why it should be a problem.

I think my car is just special... like a hot women that's hard to read... lol!

I like the fact that it is a Dynojet he has, as that makes it slightly more comparable to what mopst other shops use.

Jimbo, Mustang is just the manufacturer of the dyno, as is Dynojet, Super Wyn, etc... and each just uses a different set up of rollers to measure rwhp. It is tough to compare a Mustand dyno reading to a Dynojet dyno reading because each operates differently. But the can be compared, just loosely.

He had no problems reading mine last time :confused:

Its hard to say, Harvey is on crack almost all the time, so its hard to say if this is a new problem or an old problem with him, we just don't know if he fixed the problem the day before & cracked out the memory sector the next day.

Thats the only issue right now.

LS1s should still be able to get a HP reading from Harvey's dyno.

Without a correct RPM pickup it will screw up the TQ reading, but if we get Harvey to print based on MPH instead of RPM you could calculate the TQ based on the RPM corresponding to a given MPH on the graph.

I'm in for a dyno session

why not bolth:think:

cuz peeps have been saying that his dyno cannot pickup a correct LS1 ignition signal or something like that - if that is the case we will not be getting TQ plot along with the HP plot.

However if we have MPH, we can use that to derive RPM at certain points in the graph and plot our own TQ curve from that

How about later in April? I probably won't be on the road fully till then, likely enough. It will also give me some time to do some tuning.

i'd be up for it, how much would it cost to go without the group? i wanna get a baseline before i put in my headers.

Mustang dyno vs Dynojet dyno (http://www.activeautowerke.com/dyno/MustangVsDynojet.asp)

Dynojets use calculate torque to accelerate a large roller over time and measuring rpm of the drum/roller for speed calcs. The weight of the drum is very important. Mustangs use an actual load on the drum that more accurately simulates real road conditions.

Good post raene.

That link is weak... Their analogy of a drum being easier to turn once moving is completely irrelevant.

A dynojet calculates HP based on the change in angular velocity of the drum over time. It knows the inertia of the drum, and therefore determines how much energy the drum gains, and thus the power exerted, during the dyno pull.

The software then calculates TQ based on the RPM from the ignition pickup.

This link does a better job of explaining how a dynojet work, altho it is a bike site :).

thats fine for you m6 guys...but not for us auto guys without lock up converters :irk:

Yeah, that does a more thorough (and perhaps unbiased) explanation. I think the first link must be a Mustang dyno vendor.

Typically 248C's are accused of over inflatiing numbers and many performance shops prefer the use of the Mustang dyno (and refer to the Dynojet as overinflating) for more appropriate real world numbers. But I honestly do not know which is better from an engineering standpoint, other than the fact that I prefer the Dynojet since it is more commonly used/widepsread, which gives you the ability to roughly compare (and I use this term loosely, because comparisons are fraught with influencing factors, depending on the operator) different vehicles done at different shops (through the internet). When you have to deal with a Mustang device, there are fewer vehicle owners out there that have dyno #'s that you can refer to.

Sleepbyu, get yourself a copy of Edit and lock the convertor on the dyno... that works.

i'm old school...carbed 407sbc, th400, 3k converter:)

Just out of curiosity..

I have a programmable engine management setup right now that runs off EPROMs in the stock ECU. Basically I have a program that I can run via a laptop and edit the stock ignition/fueling maps, TPS tip-in, cold idle, yadda yadda and then save the .bin and burn it to an EPROM with a chip burner and pop in my computer to run the changes. The program's called Uberdata and it's similar to Hondata but much free-er ;)

I'm wondering if Harvey would have any objections to running a system like this on his dyno and possibly making some small changes to the fuel + ignition maps. It takes maybe 1 minute to burn a new EPROM and pop it in the car.

Anyone else using nonstandard systems that has had Harvey tune their car? I'm planning on installing the turbo before the summer and I am NOT racing untuned. I plan on doing the basic a/f curves with the Innovate LM-1 but I'm no professional so I want someone to look it over afterwards.

I'm In too, I want see what she does b4 the headers
go on. I also have a friend who wants to do the run.
Cheers...:D

Haha! Oops. Pointless suggestion to you in this case. ;)

Go to SNK Racing. I can call them if you like to set up some time for you guys. I garantee that it will be cheaper although I have not heard your price from the other place.

Standard rate is 100 bucks ish correct?

Anyway, Let me ke know

They have a dyno jet and it is on a hoist. 248C as the same one as Resnicks and WILL be a better rate. Customer service is GREAT!

Call me if you need.

I am dynoijng my car there next Sunday! I have 4 hours scheduled ;) He works with you to make sure he makes YOU happy.

it's all good:cool:



Duane. how much hp do you think you'll make:think:

Are you coming out to mrp on the 26th?:)

I'd like in too but depending on my work schedule. I'd be a last minute entry or maybe fill in for someone who can't go. :)

I'd be into it if we go to SNK's. Harvey is such an ******* that I won't have him touch my car or get my business.

I already put down over 500 but I had some issues with boost leaks etc.. Always something :rolleyes: Now I think I have everything ready so I am going back. I am aiming for 550 + plus the intercooler kit and then nitrous on top of that.

I have my M/T ET streets and need a few other things and I am good to go! maybe out there for the watch but not sure if I am racing until weather is a little warmer. Never raced with slicks before so I don't want to risk anything.

Let me know if you guys are planning to get a GB on the dyno as I would be happy to help.

Duane

Damn, I was hoping the first Dyno day wouldnt be until May sometime. If things get pushed back, Im in.:cool:

Sounds like more people will show if you change to SNK Racing. Can someone tell me where SNK Racing is and if we can buy Dyno time below $100 that would be a plus. I have a LT1 and had no problem at Harvey's dyno but I did notice that he had problems with a LS1 TA.

SNK is in Richmond.

Again a great place to go and good prices. I can call for you guys if you like. Let me know how many people are wanting to go.

Duane

Does SNK have a website? What is their history? (eg: any fast cars that they have worked on?)

Well considering the first Friday night Street Legal will be on March 26th, I'd like to Dyno before I hit the track.

I agree with bunker. I feel like Dyno day should be March 20th or 21st. Before Mission's opening nite for street legals I would like to have my car dynoed before also.

whos all going to the first street legals

i am if my car is back together:think:

I'm there 100%

SNK's has a website. Google search it, i can't remember what it's callled.

www.snksraceit.com The website doesnt do any justice to the work he can do. Incredible frames and cages. Gotta be the best Ive ever seen. Trust me...Ive known Shane and Patti for 7 years and he definetly has worked on some crazy machines. Hes good buddies with the boys at CC Racing and is a real easy guy to deal with. 604-274-5825.
Kris

I'd much rather avoid going to Harvey's dyno

Shane will do whatever it takes to make people happy. All I can say is to swing by the shop and take a look around and check out some of his pictures of cars they have worked on and the 2 cars he is doing frame up tubs on. 1st Gen Camaro and 94 RX7. You really need to see his fabricating and welding work first hand. The last cage I saw that he built was certified to 7.50 and was there to watch the inspection process and it pass first time without any adjustments needed. His cages fit better than 90% I have seen on this site.

I can vouch for Shane's work. He does all my fabing and welding!

I'm all for trying them. What the heck. I won't be ready to dyno till April though. Likely mid- to end of April, but I may be rady earlier. Not that I'm doing much... just the car isn't on the road and I have no time.

As I sated > They are great guys to work with. Well, and girl's too ;)

I am going this Sunday to dyno my car and they are not even open on Sunday's ;) That will tell you what they do. CUSTOMER SERVICE with a smile!
Their cages are top notch as well!

Can't wait to go!

Me! :) Got ma slicks, getting my backup axles this weekend (yep it's a Honda)... hoping for 13s shifting at 8500 on 22x8x15 :D

Hey Raene! Good man!

Nicve to see a civic get in the 13's ;)

I have slicks as well but not sure if I will be ready for that weekend. Still working out a few lil bugs.

Duane

I will be there for sure to watch if I don't go racing. With vid cam!

Hey thanks :D Yeah 13s is still pretty sad but I think that's about all the little engine will do.

But later on in the season... let's just say Payam would be happy, something is going to fall out of the sky and land in my engine bay and hopefully knock a second off my times :D

HUH? What would that be "falling out of the shy" LOL

Duane

A spinny muffler :) It's sitting in my room but I ain't putting it in until I get a wideband!
