McDaniels Rally Charger
 

Roger McDaniels made a badass setup
377whp with barely any lag.

Re: McDaniels Rally Charger
 

As far as I can tell the blue curve is with the twincharger. So he makes 354.7whp peak, but he makes a lot more power/torque in the mid range.

Re: McDaniels Rally Charger
 

Reading what he says again, I am wrong.
The 354whp is with the twin, thats why he says he lost 20 at the top end.

Re: McDaniels Rally Charger
 

It's still incredible really, so I sent him an email. Think a jrsc + a 14b would suck really bad in the topend on a z6? If it does, it should have a really flat torque curve.

Re: McDaniels Rally Charger
 

You read it right, I lost about 20 up high and gained about 50 down low. I just got it on the dyno tonight, so there's some more there, especially with some cam tuning, but it works way better than I thought it would; torque delivery is smooth as butter and you can't feel the transition between SC and turbo.

Re: McDaniels Rally Charger
 

Torque delivery is unbelievable, so much smoother than with just the turbo. It's much easier to control the power. I think the top end hit is from the higher air temps and the circuitous air path. The air temps are higher than with just the turbo, but lower than with a high-boost JRSC setup.

Re: McDaniels Rally Charger
 

Heh well I think it'll be an unending process. I'll stick with my 14b setup for now, since I've spent so much time and money finding a good turbo and that kind of thing. Then perhaps a jrsc/14b twincharge setup. Then a t3/t4 or something with bigger injectors and the twincharge setup. Sheesh at least I bought a big 8" fmic so that won't need upgrading soon.

Re: McDaniels Rally Charger
 

Yeah, I'm still tweaking. I think some cam adjustment will really wake it up, gotta go find my adjustable cam gears.

Re: McDaniels Rally Charger
 

Oh wow I didn't even know it had stock cam gears. Is the motor completely stock?

Re: McDaniels Rally Charger
 

gay. buy a mustang. right whitney.

Re: McDaniels Rally Charger
 

It's a sleeved/bored B16 with forged internals and 8.5:1 compression. The head is ported (RLZ Stage 2 port for boost) with a Ferrea valve train. I had some Skunk2 cam gears laying around, but couldn't find them when I was assembling this motor a couple of weeks ago, so I bolted the stock gears on it. I'll hunt down the Skunk gears and put them on it this week.

that crazy dude

Re: McDaniels Rally Charger
 

Very interesting. I gotta tell ya im real surprised you only lost 20whp having to turn the supercharger with hotter air temps and everything. Get some slicks and post timeslips. Im real curious to see what itll run. Nice work

Re: McDaniels Rally Charger
 

If I'm not mistaken he was running low 12's on his old turbo set-up but don't quote me on that one.

Re: McDaniels Rally Charger
 

That's right, it was running low 12's. I'll probably get it to the track next Thursday to see what it does. I've still got a couple of changes I want to make to the setup to fill in the bottom end and beef up the top end. I'm hoping to have it in its final form next Tuesday for another dyno session.

Re: McDaniels Rally Charger
 

whats the motors set-up? other then the turbo/jrsc.

Re: McDaniels Rally Charger
 

he had it posted over on carolinahondas.com but the site is down now.

Re: McDaniels Rally Charger
 

so he lost 20hp with both of them goin at the same time as upposed to what? I dont understand where or why he lost 20hp, is that just from the tuning of it?

Re: McDaniels Rally Charger
 

The setup is sequential so they dont both go, only one at a time.
He lost 20hp after the whole S/C install.

The turbo alone at 18psi made that power.

Re: McDaniels Rally Charger
 

he bypassed the s/c in higher boost levels so it was only getting the air from the turbo.

Re: McDaniels Rally Charger
 

I don't know how he by-passed the supercharger? the ------- thing sits right infront of the intake ports, the air would still need to go through the super charger wouldn't it? and god knows what kind of ------- huge restriction those pieces of ---- are.

Re: McDaniels Rally Charger

he bypassed it so it would stop making boost.

Re: McDaniels Rally Charger
 

I had a thought one night lying in bed. What if you were to have a dual intake manifold type setup with a JRSC on top with another manifold underneath it. I was thinking that the fmalge could be cut off the bottom manifold and it could then be welded to the JRSC's at a shallow angle so that it would rest pretty much right up against the underside. Then a flapper valve could be fabricated right at the junction of the two manifolds. Say you wanted the supercharger to make boost to 8psi then when the turbo could make more psi it would switch the s/c off. The flapper valve would allow whichever device, turbo or jrsc, that made the most boost to put it into the engine. Like, it would be a free floating type of valve that's attached on one side. The pressure of the turbo making lots of boost would force the valve into the "up" position, blocking off the jrsc. The problem I could see happening is pressurized air going up the wrong side of the manifold, like into the jrsc or the turbo (if the jrsc were blowing). It's hard to explain, but I have a picture of it in my mind. 2 tb's, 2 im's welded into one.
