Dynamometer Results & Comparisons - Straightline dyno tune!!!

lid, headers, borla, g5x3 114 lsa, and prc springs!!!!

baseline 365 hp 336 tq
tuned 402 hp 364 tq (mustang dyno)
tuned 454 hp 393 tq (dynojet)

so what u guys think!!!!!!!!

definitly recommend them for any type of work :cheers:

Beware, U may get some non-believers. My post had a few. I had a head and cam car and made a lil more then U and got Flamed, so beware. A few also mentioned that there dyno has to be calibrated WRONG. Either way, good luck.

But I definently recommend them also. Best bunch of guys ever.

numbers for the mustang dyno seem correct, as far as the dynojet conversion ? it seems a little.....inflated ? nice numbers none the less

What kinda heads do u have, i didn't see any listed! :judge:

I believe it is a cam only car, correct me if i'm wrong.

Are those actual dynojet numbers, or were they 'converted' from the mustang dyno pulls?

converted of course. Unless he is spraying it!!:)

Anybody know the conversion process? It looks like it just adds 12.5% or something.

There is no set 'conversion factor', as mustang dynos can be calibrated, dynojets can't. I'd say the mustang dyno numbers are pretty close, maybe a tad low.

What kinda heads do u have, i didn't see any listed! :judge:cam only and stock heads!!!

LOL!! tell me someting i don't know but hey the dyno never lies!!!!

Just go get some track numbers and back it up. That will quiet everyone, maybe.

cam only and stock heads!!!
thats the second impressive MD pull ive seen in as many nights.
Congrats man, enjoy!
How do they convert MD load bearing pulls to dynojet numbers then?

Just go get some track numbers and back it up. That will quiet everyone, maybe.i'll be at 41 this sunday for sure and c what happens!

How do they convert MD load bearing pulls to dynojet numbers then?thanx for the comment but i don't know how they convert those #'s but its good enough for me(mustang dyno :devil: )!!!!!

i'll be at 41 this sunday for sure and c what happens!

Me too. I will have a red Z with a sunoco hood. I hope I don't take out the second Spec S4F this weekend. Replacing the last one wast a bitch.

Hope to see ya there.

FWIW, the 454 rwhp isn't legit. Take the car to a dynojet and see what you put down. :)

I've dynoed on Speed Inc's dynojet and Straightlines mustang dyno and the dyno jet was 24rwhp higher.

What I posted in the other thread

For all the non believers, we recalibrate our dyno at the end of every week. We dont feel the need to lie to the customer about our mustang numbers, because most that come in here are coming because they know what a mustang dyno can do and that they arent looking for High numbers.

When it comes to this, you can search our previous posts in this forum and see how I feel about the "Dyno Queens", I think its funny honestly. I could care less what my car makes as long as its tuned right and giving me the numbers that I want at the track. When we offer the customer the dyno jet numbers its because, most LS1 guys want the bragging rights and its just a extra benifit to offer. When we change the calibrations, we do it by the way Mustang told us to do it. I have noticed that they do show a little high and we tell the customer about it.

Either way you need to take some of the comments like a grain of salt, because when I tell people I went 10.40s on a stock LT1 shortblock, Trans and a 10 bolt, cutting 1.43s on spray, they seem to be sceptical, but its funny to see their face when your doing it at the track!!
:drive: :drive: :drive:

:drive: :drive: :drive:thanx again for the tune, even though i knew we would have some non believers here but hey thanx again!!!! looking foward to doing business with u again :cheers:

thanx again for the tune, even though i knew we would have some non believers here but hey thanx again!!!! looking foward to doing business with u again :cheers:Nobody disbelieves the Mustang dyno numbers. It's just the dynojet conversion that is off. The only reason no one believes the dynojet conversion is because even the LG shop cars with that cam only made around 420 and most real world customers make a little over 400, just like your mustang numbers. There's no reason why your car should mysteriouslly put out 30 more RWHP than the highest dynoing car with that cam. It sounds like straight lines dyno is very closly calibrated to a dynojet.

someone needs to help out this company getting their dyno right cause somethings wrong with their dynojet....did i search for your setup and cam and all...what did i find?
414 with nw TB!
454(with very very ported heads)
386
396
obviously these numbers are inflated.why is it that people coming out after they get a tune there all of a sudden have huge number not even close to others.you realize that youre making 5 hp less than a heads and cam car with bolts ons???no one sees anthing wrong?
i believe the mustang but their dynojet conversion is WAY off like he said,who gets 50 HP from a mustang to a dynojet???

Yes at this time Im not concerned with the Dynojet numbers, we just do it for them. When we get time we are going to some testing with some other dynojet dynos in the area and get a average number that maybe we can get a closer true dynojet number.

I see nothing wrong with the numbers. You can increase or decrease rwhp on a mustang dyno easily with just changing the load. The dynojet numbers could be right. Remember we have had several cam only cars dyno over 440rwhp.

good idea,i think thatll help you guys out alot and get things where you need them.good luck,still good numbers on a mustang dyno

but not on a regular basis from the same company.....maybe you should read the other thread of a z28 with a low 230 duration cam and stage 2 PP heads making 477..ie what a stroker or boosted car will make.and this is on stock injectors that "arent maxed out"

Remember we have had several cam only cars dyno over 440rwhp.Very confused on that one.:confused: The fact of the matter is, NO G5X-3 cars have dyno'd 440rwhp in a cam only application. There is nothing diffrent or "speacial" about his application to make us think that he should dyno that high.

yes yes thats what i was saying...but lets not keep bashing...the company said they need to fix some things and get it in order and then the numbers will be more accurate and more realistic.if the companys willing to admit they have to fix or tweak stuff then lets leave it at that.Good luck StraightLine Inc hope you get it worked out.and those are good mustang numbers CHIWS6 congrats!

dammmmnnnn lot of contreversy on the #'s but hey i went to the track today and usually run 13.1/109 and after the cam my best was 12.6/113. my 60' was 2.0 and i know i need to improve that but over all , i am definitly happy with the setup!!!

113 mph? I was looking for like 120 plus if your putting down even close to that much... even with a 2.6 60 foot.

I've tuned converter only cars to far faster than that...

now now.no need to bash the guy.i have a friend whose running 12 flats with intake exhaust and a bit of suspension so...its pretty obvious that hes not making the 454 he posted(though not his fault) but still nice time with just a cam.bet it feels good to break your old time and up your mph!now lets just let the number wars die cause its quite obvious to everyone that they're not correct.congrats though

Hey I'm happy with your results and Tony @ Straight Line is a good guy. I was just expecting some stupid fast trap speed. What did the car quarter mile on his mustang dyno?

BTW I'm sure the car sounds mean. Props to you.

Ok I just saw this post and Im gonna have to speak my mind, rich dont hate me. We have a bone stock z28 that put down right around 304 mustang numbers and goes consitant 13.0s at the track and its auto and on a street tire. Im gonna have to say this is driver error and unless I or one of our good drivers are in the car, Im not gonna trust the number. Especially if its not on a good slick and especially if its a on a street tire with a 6 speed. Rich next time you get to the track let me hop in there, I can bang some gears and Ill put a big smile on your face when I get the timeslip.

I was there with Rich, he was shifting at 6K. I suggested he shift at around 6500rpm instead, I honestly felt he was leaving a lot on the table. On another note, those of us who had run before were about 2.5mph off from our best trap speeds.

It would be awesome if you could come out with us and take a crack with his car!!

41 was off about 3 MPH on average yesterday. Hooked great as my driveshaft found out.

Yes throw on a good set of slicks and watch that 10 bolt go boom! Mad props for having a tuned car at three different power points so no need to sink much if any cash into a five hundred horse car.

he should be shifting higher.

hay tony, i wont bitch if my numbers come out high, lol.

hay tony, i wont bitch if my numbers come out high, lol.
HAHAHA Thats good :)

Rich its sucks that you didnt get any advance ground into the cam so you could bring the power band down. You should be shifting at ATLEAST 6500, the hard thing is though its a BEOTCH to shift at that high of RPM unless your a killer driver. If I remember correctly your car was almost pulling on the curve till 6900. Depending if you went with the double roller they have the marks on the rollmaster were you can advance it right from the lower gear. That would be something to do later on.

No one seem to say anything with his MPH either, that is definetly a High if not quicker 11sec MPH.


PS anytime anyone needs a driver at the track I will gladly whore myself out at no charge :usa: :pimp:

PS anytime anyone needs a driver at the track I will gladly whore myself out at no charge :usa: :pimp:thanx Tony, a shift light will definitly help and im still learning how to launch the car with the cam because it's like trying to learn how to drive stick all over again. the mph should be higher but hey im improving :cheers:

This car doesn't have an LSX intake, waterpump, pulley setup, or ported TB from what I can see. I call a big stinking pile of BS.

Once again, you can have the best of everything but if its not built right or matched its not going to run right. I know people who have ALOT more then him and guess what they are just about the same area. There is no stinking pile and if he had a decent rearend and let me stick my custom laughy gas setup, I bet you that we could walk right past ya, yes I love a challenge. Im not out to put fake numbers out, Im out to show the real thing. I speak it how it is, I could lie to them and make them happy but down the line what happens when they come back complaining?

Ask around the cars we come out with are next to nothing, yet they are always stuck racing fully built cars and somehow we still manage to come around them.

i dont think driver error is gonna make up for about 8+ mph

hell a gopher could driver a 450+ rwhp car to 116mph, nevermind the 120+ where it should be

my car is probably wont break 405 rwhp, it weighs 3500#'s, and it traps 120-122 every pass

btw this is not directed to the car owner, just stating the numbers look a bit inflated

Don't forget this car had a 3750lb race weight!

means nothing...he sshould still be deep into the 12's if not lower with those numbers.let the company get it worked out then he can repost.good luck

hay tony, if ya have my car done tonite, ill let you flog it 66 this evening :)

I made 404rwhp on a dyno jet with a 12bolt and 6-speed at 3800lbs it went a best of 12.1@114 and was consistent 12.3@113 so how how much better can it get for shifting at 6k and being on a nitto?

Guys we do not stand by the Dynojet numbers, we know they are high!! We have said that 4 million times.

THANKYOU i wish these people would realize what you said earlier and leave it alone til you get it worked out!

LG cams are fun. :)

I had a LG cam once, then I went to the Darkside!

On our red car we made 340rwhp through a th400 and a stock 10-bolt on a dynojet. The car goes consistent 118 mph in almost any air and at least 116 in the blistering sun. We've done no weight reductions and the car has extra weight in it from misc things (stereo, nitrous bottle, th400, sfc's, etc).
