Putting my car on the Dyno this weekend...what will it make?

383 LT1 8.8 Compression
LT4 Edelbrock Intake
Fully Ported AFR 227 Heads flowing 31x/22x at .600 lift.
Jessel Shaftmounts 1.6
Custom Blower cam 236/242 with .576 lift
D1 Blower with a 7.65/3.70 pullies making right at 15psi
93 Octane fuel + AklyControl Kit
Moser 12 bolt 3.73 gears
T56 with a street twin

Car made 640rwhp with a CC305 cam and Stock Ported Heads with a 7.65/4.20 pullies making right around 14psi without the intake pipe.


Anyone wanna take a guess?! Sorry no money involved :D

Marcin I'm gonna say 740rwhp and a tad under 700rwtq. I'm probably off like a MOFO but who knows? :D Good luck man! Will you have any vid footage?

aww, no money??? Well, i'm guessing what i guessed in the other thread, 760.

I'm thinking 687 HP and say...735lbs ft of torque.

-B

690rwhp/640rwtq without intake pipe

702rwhp

720 rwhp

wow there is a lot of nasty lt1s being built latly... finnaly getting tired of younger bro pushing out cars around? lol

What RPM's are you running it up to?

I'd say 675 or so. Is this on a Mustang dyno or a Dynojet? (I am guessing on a dyno jet based on the numbers)

678hp/615tq.

Good luck

Good luck

lol..maybe with a 200 shot ;)

697rwhp 660ish rwtq


not bad considering a lot of things....seeing 15psi thru the crapy ATI Inlet with a huge K&N...i was tempted to take it off but decided not to cheat :p

i am going back in few weeks after i get a custom 4inch elbow and true duals..Hopefully it will hit 750 then :bow:

Awesome numbers especially through a heavy moser!!! How much of that power do you think is related to the heads?

Also are you running off of the stock computer?

yeah, stock PCM, stock OPTI....just a MSD Coil...not sure how much the heads did or the cam or the smaller pully...for comparison sake this is my old dynosheet...the 640 number was done with a open blower..no intake on it AT ALL...591 was thru the same intake as today...Stock ported heads, CC305 and 4.20 pully made around 12 psi with the intake 14psi without...

I am putting a custom elbow on in a few weeks myself, but it will be another month or two before I get to the dyno. Please post up what difference the elbow makes in boost, and then when you get the new dyno, the difference in power.

who is making your elbow?

I got it from Lisa33. It already has proven to work well on her application, and a couple other guys on here with Prochargers.

I got a better way, an HKS style air filter that mounts directly onto the blower, hard as hell to put on since it is right below the headers, but it fits. Bought it off ebay for 15$ shipped.

exactly what i have been looking for...whats the part number ?

good numbers saint, I'm impressed ....knowing it has a little more in it, I wish I could afford a blower.....maybe one day

crap, bought it along time ago and i tossed the box... i'm searching ebay but can't find it. I'll keep looking.. i'll have it before long, keep checking here...lol

I got ~ 10-11 psi w/ the 8 psi pulley combo w/ full bolton car that ran 13 flat...maxed out my 38# injectors @ 110%DC by 6,000rpm :)

ok, i can't find it anywhere on ebay anymore. The two sellers that were selling them no longer carry the "sphere" type, they have a slightly smaller(thats too small)"cone" style.

The filter i got has a 3.75" coupler and is i believe 4.25" outword. It was listed for a toyota for some odd reason. Its the HKS style. Hope this helps...

will this work?

will what work??

Beautiful engine and nice numbers.:)

soo close to 700, i would have had to take the filter off. lol, nice numbers.

I originally considered this as well, but then realized it would'nt help me out as much as I thought since you need some kind of inlet to help crank case ventalation and ventalation for the opti. Basically you need a spot where you can run these two lines to the inlet to help ventalation.

I still have that, i drilled a small hole in the rubber hose. Worked perfect. There is just enough extra off the blower to allow this.

What rubber hose? It looks like the filter is directly attached to the blower.

Vk I want to see some pics, I am running a -6an fitting off my LT4 intake into a Oil/Air seperator and I needed a -6an bung welded onto my 4inch Elbow. Just wondering If I could weld something with this peice???
Have any pics, how close is the clearence from the headers???

No pics of it on the car, my car is without motor and tranny since the blower did a number on the stock bottom end :)

There is about ~2-3 inches of clearance from the headers, and maybe 2 inches from the steering arm.

The filter itself is a yellow "foam" and then it has a metal ring that holds it onto a yellow rubber hose which you hose clamp to the blower inlet. You actually have enough rubber hose between the blower inlet and the actual filter itself to drill a 1/2" hole to add a vent hose to. I have both valve covers venting to a oil can and then a line to the rubber hose of the blower air filter.

I'm still looking for a place to buy the air filter i used, as soon as i find it you'll know.

those heads are bad ass

well, i still can't find those air filters again. But if you do a search for mushroom air filters you'll get ones that are almost exactly like the one i got. One company called Ractive makes alot of them, but i can't find big enough ones.

The inlet of most Procharger blowers are 3.5", i used a 3.75" inlet filter, all the ones i'm finding are 3".. too small.

I actually tried mounting a mushroom filter on my car at the dyno, but it wouldn't fit with my LT headers. I'm still not 100% sold that it will give the proper ventalation that a large metal inlet tube will with a much larger filter. But if it works for you, then it should work for others.

It may not have more "suck" for a vent tube for the valve covers, but i bet it flows better then having any kind of metal inlet tube and then a filter.

Breathers on the valve covers should be good enough anyways... why would you need a large amount of vacuum?

actually inlet on the procharger is a 4" :cool:

Actually we are both kinda wrong and kinda right :)

The C series are 3.5", the P600b to F1 are 3.75" and the D1R and above models are 4".

Trust me when I say, you can never have "enough" ventalation. If you are running a D1SC or bigger style blower at more than 13#'s of boost, and only have ventalation throught the tiny breathers in your valve cover, they will be overloaded at trying to relieve the pressure. This can be bad. You need as much possible ventalation as you can figure out to use, as with running this much boost on a LT1 which will build up a considerable amount of pressure, which is not good for the motor at all without proper ventalation.

You are correct that it probably will flow better. But it is taking hot still air directly from off your header, while others with a inlet tube to a larger filter are getting it from the cool air from the ground that is blowing directly at the filter. If you have an intercooler or running something to cool your IAT's it will have to work harder to keep your temps down compared to the inlet tube. Just some other things to consider.

If your sitting still i believe your correct, it will suck its hot air from around the headers. But it sits a few inches below them, well low enough so that when your car is moving it would pickup the cold air flowing under the car, plus heat rises.

Sounds like you've got alot of blow-by issues if your having that kind of problem with needing massive amounts of venting. If you have an intake gasket leak, hole in your heads, or piston rings that are not sealing (try using gapless next time?) you will have major issues with blow-by.

Installing the vent tube into the "suck" side of the blower is recommended because it "draws" out the gases inside the engine crankcase, not to get all of the buildup out (blow-by). If your having issues with blow-by then venting to the atmosphere would work just as good as venting it into the blower.

I guess we might have to agree to disagree on this one :) . Everyone I have spoken with says you simply need as much as you can get to ventalate the crankcase pressure. True, the breathers on the valve covers will help, and probably even do the job if you are running 10#'s or less. However if you are running 15#'s + on a D1 or F1 application, or even a maxed out T-Trim setup, the small breathers on the valve covers simply won't be enough. Bottom line IMO, and the opinions of different speed shops, and tuners and people I have spoken to with this type of setup is, you want as much crank case ventalation as possible.

Well, I'll agree with you that getting as much crankcase ventilation as possible is a good idea :)

I've heard you can get an exhaust ventilation system for pretty cheap and that it works really well. I've considered this option, but probably won't act on it until a turbo kit is in the works :p

I have seen the exhaust ventilation setups as well. They do work well. I am only running about 16#'s of boost on my setup, and I have two large breathers on each valve cover, along with the ventalation to the inlet tube in front of the air filter. Unfortunatly, I did'nt have very long on this setup before I put it away for winter for the year :cry: . But from what I have seen, this should do it for me. Some guys running the F1 are using the exhaust ventalation setup though, and it works well for them.

having breathers and running the pipe into the intake is pointless...it needs to be a closed system so u can create vacume at wot.

I think he's right. And i agree. :D

I agree, and this is not what I am saying. I am saying you need to have the crankcase ventalated from the valve covers to the inlet tube of the blower. NOT from the actaul intake on top of the motor. Then you would be correct as it would be a vacuum leak.

you need to get rid of your breathers, and run the valvecovers to a T then into a oil/water seperator, and then to inlet on the supercharger intake :p

Saint just wondering How hard your spinning that D1 too???
what is your pulley combo and what are you reving it too??
I think the D1 spins to 65000 instead of the D1SC to 62000??
Just thinking you have some more boost left in it. nice numbers how do you like the Edelbrock intake??

i have plenty of RPM left in the D1...running 7.65 and 3.70 pullies...spining it to 6300 or so. Next step is get rid of the ****y ATI intake, and get a 3.40 pully..Should be solid 5lbs gain if not more :eek: I am hoping to crack 800rwhp next time on the dyno. Oh ya i am goin to get rid of my horrible ypipe set up in favor of 3 inch true duals. :p

Do you happen to have pictures of this? Its not rocket science but I would like some ideas on a clean way to route all of the tubing with the oil separator.

yea..ill snap few pics hopefully tonight..i just put it on last night :D

Good luck with the setup saint, and let us know what she does.
