What do you want pics of right now?

Once things start to come in I will start a new thread...

 

Careful your beast doesn't get whooped by cars with 200 or so less hp. What you doing for traction? and then once you figured that out....that's when stuff starts breaking....lol

 

Oh don't you worry about the 200whp cars my car should hook fine... Suspension is the 1st thing I took care of and will hopefully be putting a better dif in as well. And Tires, well I will soon be putting some stickies (Drag Radials) on. Also, can't do anything about breaking parts!

Thanks for you concerns; oh and btw considering your tone don't let me see you on the street or I will whoop you too!! :-)

 

Hey John....following this thread with interest. If your luck is as good as mine you might pull back on the whoop *** talk a tad! Bites me every time!! I wish you the best with your new build. I hope you have a competent outfit doing it for you?

 

Hahahaha your probably right.... And once I have everything done I think I will probably be more modest than I was with my previous setup!!! What kind of luck do you have with whooping up on people??? Also, I def. trust this shop with any work I have and know they do great work!!! Thanks bud and hope to have some pics of the engine for ya next week!!!!

 

Not possible for 2 reasons

I don't street race
The car is not street legal, nor streetable.

Now when my build is over (finishing fuel cell and firewalling trunk at present), I would love to see our cars race down a sanctioned 1/4. I am expecting low 9s from mine....how about yours?

 

I don't even know why I'm getting into this crap... This thread was started to just to get some "Friendly" advice on a build I was starting! Seriously Steve I wish you all the best but honestly unless you have something constructive to say just stay off this thread please. I hope your build goes well and exactly like you plan!!!

 

And I would like to see you have much success with yours as well.

 

Thanks and let me know how it turns out!!!

 

FYI;

8.5:1 would not make much of a difference in the street with a 5.0L stroker as it will make more torque than the 4.6L or at least similar.

Secondly I really don't see a reason to exeed 9:1 compression unless your running e85 which is hard to start in the winter and your contemplating driving the thing in sub freezing weather.

in any case, the brenspeed 9.5:1 block + the ford racing cnc ported heads with 53cc combustion chambers should bring the cr down a bit as the stock combustion chambers are 43cc.

Good luck with the build, if its available to you do run e85. Its basically race-gas for the street. There are quite a few 700+ whp cars around here running on e85 some are running as high as 35psi.

Keep the shiny side up.

 

I understand some people's ploy to running E85 due to the fact it will burn at a lower temp but a couple of things you need almost twice as much fuel than you would need in a reg. gas powered engine and the availability isn't very good down here in S. Fla... Plus once the tax breaks are repealed I see the cost of E85 going way up just like Race gas...

I don't really follow why you think a CR of 9.1 is high??? As for lowering the Brenspeed motor w/ diff. heads well I already have a set of aftermarket heads so I am def. not going to spend money on another set.

Anyways, I happy with my setup; CR somewhere B/t 9.1-9.3 and a Whipple w/ around 15-16psi...

I appreciate your help and advice!!!

 

Pump gas depending on heads & intercooling can take up to 23psi, I had a friend melt a forged piston @ 32psi with 9:1, he rebuilt the engine with 8.5:1 and dint have problems again. FYI; he was able to run a different tune and made the same power if not more with it.

In any case, yes e85 needs allot more fuel but its also relatively safer on the engine with high boost. Some guys run two sets of injectors, the main ones supply fuel up to 17-18psi and the second set are placed much higher upstream of the runners providing a cooling effect and more fuel for higher boost.

As for the aftermarket heads, you can have the combustion chambers ported to lower the cr.

In any case, no use of me bench racing, your the guy doing it, I wish you the best of luck. Sometimes I need to remember whats good for one is not good for another.

As for e85 going up in price, its possible. But new law states that at least in NY, every new gas station built has to have an e85 tank in it. I am guessing they would not do that if the price was going to be sky high. Then again this state is ruled by idiots so everything goes.

Post pics when you can. Have allot of fun and keep the shiny side up.

 

Was this on an S197?

 

Hahahaha, I have to respond to first to the "This state is ruled by...", That is HILARIOUS and SO TRUE!!!! Ok, I understand your rational for saying the prices won't go that hi considering they are putting a tank in each new station but politic is an ILLOGICAL land made for people who want to do the opposite of what a sane person would do...

I know you can run higher boost w/ a lower CR but you may possibly lose some low end power (but considering the whipple makes instant boost it shouldn't matter)...

I love the idea of two fuel sys but that seems pretty pricey and a little high maintenance...

No, I completely appreciate your help and advice I mean as I was telling "Steve" the guy who wrote below you that I know a little bit about a little bit and talking to guys is helpful in looking at different avenues that I haven't thought of yet... I REALLY appreciate it and welcome the help!!!

 

Yeah that is interesting. Sort of a halfway step towards a benefit of DI.
Because doesn't DI allow a higher compression ratio because the fuel is cooler at the cylinder's injection point?

 

FRPP's site says the NA 4.6 3V shortblock is 9.8-1. But their beefed up shortblock for superchargers is 8.7-1. So they seem to be fine with under 9 for FI.

I'm not quite sure what you are getting at but to be honest I was going to go with around an 8.5 CR but then changed my mind and now I'm going 9.0 - 9.1 something like that... Can you further explain what you are trying to get at???

 

That your first thought was closer to FRPP's design than going over 9.

 

And are you saying I should've stayed with my initially thought??? Are you saying that so I could save some money??? I am just trying to figure it out... Sorry I am not trying to be a jerk, just trying to understand.

 

I just happen to be browsing FRPP's site and noticed the difference between the blocks. It reminded me of your discussion here.
So it seems like Ford Racing opted with the lower compression. It would be good to know how much boost they recommend for it.
But I'm not the guy to ask advice about it. Just pointing it out because it counters what some have said.
