MaYbE?!

 

Is not nice to mess around with a guy that gets paid to play with explosives! I want numbers right MEOW!

 

Sorry, I have to wait just like all of you have to wait. Bill has numbers, but will not tell me! haha cause he knows Ill spill all the beans! Id say we are going to wait on saying numbers until the big meet on Sat and just let everyone have it then! Sucks you wont be here!

 

Damn you scooba steve! That's cool. Once they are released please drop a line on here for me to see. That is all I ask. I will go play in the 100*+ weather now in the sand until then.

 

I will say that I envy your know how/ability/opportunity to blow **** up. That's right up there with race cars in my book.

 

so how much is this system looking at ?? lol sorry guys if this has been already talked about i'm being lazy and looking for a quick answer

 

It is cool coming up with new ways to destroy ****! We got bored after a ton of demo shots in Afghanistan, so I started taking flare pods from aircraft crashes and putting them un top of my shots. The shot would blow with a huge fireball, and then flares would burst out of the top of it! Plus, you still get to feel the kick from the bang. Way better than the 4th of July IMO.

 

Going up to Hahn Racecraft tonight to get some videos of it on the dyno... Some with pump gas for sure... MAYBE some others with 100 octane? WOOT! Then some videos of it street driving with prob no traction! Stay Tuned!

 

I want t3h 20g...

 

Im hoping my 20g kit (partial, no intercooler or charge tubing) will be waiting for me when I get home tonight.

 

I say....540 whp

 

Damnit , I wish I could make it to the midwest meet

 

I want the Super 20G NOW!!!!!

 

Tell me about it! I have a super 20g infront of me.I just need some motivation to install it.

Hey Bill,
Do you have a time frame for when your releasing the 20g kit?Ive been waiting for it since last summer,lol.

 

what type of dyno?

if its a legit, load based unit (not load applied) thats got its SAE cert then i say a MAX of 650-680

flow numbers govern this by law-o-physics.

stock head at 580CFM Xmax13% gain with JBP head = 655CFM

useing the lowest agreed number for cfm per HP 1.4cfm/1hp

655 / 1.4 = 468.

adjust the flow numbers for the boost (20psi)
28.5/15.5 = 1.8

655X1.8 = 1189

1189 / 1.6(more commonly used for power per CFM)=743

factor in lack of exhaust port flow contaminating the air charge, plus restrictions in the intake path, and lower air density with heat and you'll lose flow as well....so i'd say 650is tops.

re-did the math to 20psi (~28.5psi map) per my data logs and you should see a max flow potential as noted above.

 

It will be nice to see this car again, seems like it's been forever since the last time we saw it at a meet. (something like 2 yrs?)

 

using that equation the stock head could put down 414, thats good enough for my setup.

 

those numbers are are from flow tests at 7kpa, or about 15.5psi absolute.

with boost the numbers increase, but the exhasut side chokes down that number as well....plus a few other variables that will take away power.

but you should see the general idea.

 

so it's probably pretty close to the max we can make on the stock head though. which brings me to a question, our exhaust ports are f'n small, but i imagine that increases the exhaust velocity correct?

 

edit your last post with a quote of my updated post on the last page.

port velosity means jack friggin **** when compared to flow.

i'll gladdy lose 50% velocity for a 50CFM bump per cylinder.

turbos are 97% mass driven, not velocity.

what type of dyno?

It is a Dynojet chassis dyno. Sorry but 470 is way low for race gas and high boost. I think you may have messed up some numbers..... But anyway, we will all find out soon!

 

So Joe, that was yesterday. What were the results and where are the vids?

 

quote updated, bear with me on this one, i know jack sh** about exhaust flow in reference to how turbine will react. right now i polished the exhaust ports to reduce surface area and increace flow(understandably not much though). i'm just thinking with less surface area it will lose less heat in the head and there will be more exhaust expansion in the turbine. i'm probably on crack, but whats your thoughts?

 

Patiently waiting for videos and still playing in the sand!

 

see updated numbers per boost

meh, your thoughts are novel and on the rite track, but that polish is going to have a varrrrrrrrrrrrrrrrrrrrrrrrrrrrrrry limited effect in the regard.
