also still learning, does a bigger turbo just increase boost? or is a big turbo at 5 psi better than a small turbo at 5 psi.
i am thinking 5 psi is 5 psi regardless of the size of the turbo, but I'm still learning and am not sure.
Originally posted by Die Ford V8: i am thinking 5 psi is 5 psi regardless of the size of the turbo, but I'm still learning and am not sure.
Nope. 5 psi on a baby little turbo is not going to move the same amount of air as that same 5 psi on a big turbo. Its at the same pressure, but not nearly as much flow. Air=Hp.
Cp </font>[/QUOTE]The mass flow rate will of course be different due to temperature differences.
Do you have any idea what the difference in intake temperature was between the old turbo and the new one at 5psi? Also, if your boost guage is in fact correct, it would seem that the old turbo was out of it's efficiency range at 15psi. </font>[/QUOTE]Its been a WELL known fact that the old turbo was way out of efficiency at 15 psi. This new turbo at 7 is running much better then the old one ever did. Old turbo ~36mm compressor new turbo 61 mm. Big difference.
Originally posted by kamarozrule: is this kit going to be for the 3.8 as well? and if it has a similiar setup, what kind of gains will you be expecting?
Originally posted by nocutt: Nice numbers...however something isn't right somewhere :( ...assuming you even have a VE of 90% at 6K RPM and flowing almost 400CFM (turbo) which will equate to about ~30 lb of air/min your max tq will never be that high...Yes I don't doubt the HP, but the TQ???, then again since hp is a mathematical derivative of TQ then the whole thing has a hole...ask for a recalibration!!
LMAo 40 cars dynoed why would only mine be off?
From a driver's perspective the car is much quicker/torquier/plain faster then it was before so Im not questioning anything yet.
BTW from my previous dyno results you can see the car has always been a torque monster so its no surprise. See earlier in the thread for those.

There is a thread on LS1tech saying otherwise. I was just quoting it. </font>[/QUOTE]Thats funny because I am quoting from LS1tech and the owner of the shop as well.
yup heard it dynos right with mti's and everyone knows mti's is high
hell I have dyno proof. I dynoes on a dynojet at exessive in the morning then went to mti and dynoed 5 rwhp more with no changes and if anything the weather at mti was worse because it was later in the day. And the 5 hp diffrence was with a 160rwhp car not close to 300. So take 10 rwhp off the 290 and then you will have a more accurate dyno. (i would think how much the dyno is off is linear because speed is so 10rwhp off the 290 would be what someone on a regular one would dyno)
Yes I have the dyno graphs to prove I dynoed twice in the same day, they both had dyno days on the same day.
I haven't talked to Jason in atleast a week, so this wasn't planned. We are both just expressing our poinions that we both have first hand experence in, thats all... no need to get upset. [img]smile.gif[/img]
I am not putting down any MTI numbers, everyone in their mother knows their dyno is a bit high, but HPEs dyno is right on with MTI. Don't confuse people and say that your dyno should be 20 RWHP more then it actually dyno'ed, thats pathetic. Thats all I am saying.
I wasn't saying anything except what a certain member over there said. His cammed ls1 made a tad over 400 at MTI and did only 385 at HPE.
Im not gonna claim my car makes more then what it did but I just thought that was interesting.
BTW if you wanna ***** about 5-10 rwhp difference on the street or track the intercooler will more then make up that difference by having alot more air flow thorugh it.
hell I have dynos to prove that, and like hawgs said even the owner says he dyno is right with MTI's that would make his a high dyno too would it not.
(MTI's dyno has always be considered to be higher then other dynoes atleast compaired to the ones in houston, heck I have proof to back that up)
You said you heard it was dynoing 20hp less, bs thats aloooot of hp to be missing, when the owner of the shop says something about HIS shop I tend to belive it.
you think you made 310 rwhp with 5 psi, no ****ing way, it cant happen physics says it cant, your car is governed by physics. your saying off a base of what 150rwhp you improved 160 hp with 5 psi, thats 32rwhp per psi aint gonna happen
Don't stop reading just because you hear somthing you like... [img]smile.gif[/img]
Chuck, Owner of HPE:
Every report I heard was that our dyno reads almost exactly the same as the other local shops. And I thought the car with heads and cam that only dyno'd 385 was a CXI car, not an MTI car.
Fran96SS:
that car was a turd somethign was wrong with it b/c a cam only car dynoed higher than him the heads cam car on nitrous dynoed like 456 the cam only nitrous both on 150 shot dynoed like 470 that car deff was wrong somewhere alot of other people said it was deadon some kid for instance said he dynoed the car a month ago and he said it was with in 1 hp of what he dynoed before

dont make me take out my corky bell book
Did I ever say the car made that much ? I know only one thing for sure! and that is that it made 290/373 3 back to back runs. 5 psi and nothing else.
You are talkinga bout a measely 20 rwhp difference which would be made up by actual street conditions anyway. You can pull out your theoretical physics all you want don't forget I am a MECHANICAL ENGINEER. I know and ahve experienced more physics theory ANd reality then you can dream of and I also think through all this **** when I get a result I knwo when something maybe skeptical. Sometimes in practice theory doesn't workout. It did do what it did and what I claimed. THAT IS ALL.

</font>[/QUOTE]I agree when I first read that I ahd not seen that response. I never claimed more hten what it did either.
So my truck is finally getting some work done, after 17 years, Oil pressure sensor went out and it’s located under the lower intake manifold. Have to...
