Default need input on this dyno graph

Take a look at this graph,will this go 9's in a 2,400lb civic with a lsd gsr tranny?
I know it has enough power but its real high in the rpm, need input.

I'll bite...Sure it will with the right parts. rota92 ran 9.85 with a d16z6 not making HP till the high RPMs. Car with him was 2300lbs.

What other parts do you plan to buy?

if you can make use of that power, it should.
i should lock it for the vague title.

hell ya just got to get it to hook u can hit mid 9s with that probably but i would deff rev up to 10grand so the car doesnt fall out of boost.
your not going to go back down to 3 grand when u shift unless u short shift. jsut have to shift high enough so u dont fall out of boost

went 10.3 with 512whp 2550lbs

That is ALOT of power for only 29lbs of boost and put that **** on a dyno jet and i bet it reads atleast 100hp less. A little insight to why this dyno graph is WAY off, first off the car in question has 1000cc injectors and a eliminator pump. Those pumps dont and cant work past 80lbs of fuel pressure efficiently at all. So lets just say this car ran a base of 50 and with 30lbs on top you have 80, that pump is dying up there by the way. Do the math and you will see that even with the injectors at 100% duty cycle the power is way less then what you see there on the graph.

Besides all of that, even if this car makes 650hp it can go 9's with a graph similar to that with the weight mentioned above. I have had a few customers go 9.8's to 10.00's with 35r in full street trim cars.

Why is it so laggy?

I see that it was stated that the car runs a 41lbs base.

I just realized that this is your car, since the car i almost done with what we are doing. When you come pick it up you are more then welcome to bring some race gas and whatever you need and i will give you 3 free pulls on the dyno to compare readouts.

Yeah, i am very interested to see this car and Joe's on your dyno...I didnt believe it when it made 750 on another Dyno Dynamics, and then almost 850 on mine.

And once he gets the car back with the cage from you, the trap speeds should tell the real story eh

Not really sure who Joe is but yes it deff should, with that power the car should have no issues trapping 165ish.

Default Re: need input on this dyno graph

so it cant make that power on a 74mm turbo? I tuned a car the other day and on 11psi with a 74mm turbo it made 424whp. The dyno wouldnt read after that because of slip but we went to 28psi I will see once the dyno is fixed what we made for power. Winstons car made 831 with 1200cc injectors on 32psi of boost. Both of these were on dynojets!

Miller you hooker call me!

I am not saying that a 74mm turbo cant do it, it sure as hell can but not with a base pressure of 41lbs and 1000cc injectors.

Yea I thought 1000cc injectors max out around 700 hp

Default Re: need input on this dyno graph

Miller is right, unless he is running some sort of regulator that has a much higher ratio than 1:1, there is no way that 1000cc injectors at 41 psi base will ever support that much power.. I'd question everything that came off that dyno.. Don't get me wrong, dyno's are just tuning tools, but if they are 100+ hp different than a few other models, then it wouldn't make much sense to quote the numbers from them..

Then again, someone could just have their info mistaken, and it is really 70 psi base pressure and 1600cc injectors..

The torque on the dyno, and hence the power, is very suspect. That is 5.97ft-lb per psia manifold pressure per liter displacement (525ft-lb at ~44psia). Just about every reasonably tuned, well-running car with good parts and a 5-spd will make around 5ft-lb per psia per liter. This goes for just about any engine combo. This would require ~20% above the norm for VE at peak and that is very suspect. Sounds like an optimistic dyno.

First off the car had 58 psi base fuel pressure. Second, the car was at 28 pounds so I'm ready to turn the boost up another 20 pounds if needed to see the power I want, after changing the injectors. But Miller I'm confused about what your saying regarding the pump. I told you the power I wanted to make and you told me to get that pump specifically. I even bought it from you. You also told me this power was what I would be making with this setup, just with 1,600cc injectors. oh yea is my cage done yet? lol....

Call up Dyno Dynamics then...I dont know what to tell you, those are the numbers that came up. It really doesnt make sense in my mind to quote ANY numbers from any dyno really unless you are comparing numbers on the same dyno to changes in the tune or the setup.

Just last week a customer came in that ran on Evans' dyno making 187, on my dyno with the same tune it made 184. (peak numbers) A previous time a customer came from Miller's dyno and made slightly less as well. I have had customers tell me even in Shootout mode my dyno read less than another local Dynojet, a Dynapack and a Mustang. He took his car to (4) local dynos just to get an average figure, and his traps basically matched his numbers.

Joe's car last year (miller, the guy with the **** brown EF single cam hatch, you told him you would let him run for free on your dynojet) made 280 whp, and then trapped 124.5 mph in the quarter. I have no idea...

I would be questioning this stuff as well, if I hadnt seen it in person on my own dyno. I think I even yelled once in one of the videos, "this dyno cant be reading right" and Rob laughed at me

I dont care about numbers, I just hope Rob gets to pull the chute on his first pass out

My .02 on xenocron's Dyno -

I had a motor that seemingly shouldn't have made the power it did on Chris's Dyno. I had a whole bunch of people, telling me that the dyno was inflated etc.....My response was "only trap speed will tell"

The 215HP car @ 2400lbs consistently trapped at 110. All of a sudden it became very believable that the numbers on xenocrons dyno were not as inflated as people had suggested.

proof will be in the trap.......but I would like to see Chris's Dyno compared to other dyno's
(for ****'s and giggles) I still believe Trap is one of the best ways to guage

PS If anyone is curious enough, I will shortly be going back to Chris' to re-calibrate "some ****".....I'm planning on putting the car back on the dyno just to if the problems we worked out...helped or hurt performance.

If any local shops wanna float a free dyno-run, I'd be happy to put my car back to back on 2 different dyno's (with same tune etc.) to give a solid answer.

(personally I don't care, as the track is my validation of Chris's Dyno)

Chris I do not recall the **** brown ef but either way if i said i would give him a free pull he is more then entitled to come get it. I dont know what it going on with the dyno but i can tell you its not right, thats all i really know.

Rob, yes the pump is fine. There is nothing wrong with the pump other then that you SHOULD NOT be running that high of a base pressure with the pump. This is something your tuner should know, the injectors you have and the pump can not support those types of pressures. Something will fail and when that something does it will probably be alot more then just the pump or injector. If you had 1600's in the car i would believe that power was possible but no way in hell with 1000's. If what you are saying is true and you ran a 58lbs base collective with the boost you are nearing 90lbs of pressure. That pump at 90lbs of pressure is nearing 500 lbs/hr and dropping fast, along with the crazy amperage draw is insane up there. I have made power with the eliminator and the pumps have worked great for me but you have to know the limits of the pump and how to use it.

Your cage is done, jsut awaiting the harness, chute and window net to get here on friday and should be ready for you on saturday.

Thanks..... Sounds great! I will be talking to you more about the pump and what pressures
i should be runing. Most of the setup on the car is based off the info you have given me
so thank you for the GREAT info.
