HMMMM not saying anything..but your getting warmer...its backwards on purpose..
Why not twins..LOL... because that block would explode with 2 of those... DONT NEED TWINS....He will be good for at least 8's with that..WTF would he want even more... IF you get below 8.50 then you have to have an SFI spec chassis...which means tearing everything out and starting over for him..
I dont see the fascination with twins anyway... with the way the newer turbos spool up>>>and the fact that they make them the diameter of a sewer lid now...there is no need for twins..

Wood is exactly right. I built this thing to race not to drive on the street. If I built it for the street, I might put twins on it for more low end fun but this thing should make enough power to push me into the 8's.
And I have a water intercooler core that is 6" x 12 1/2" x 13" that I need to get some aluminum for to make the end tanks with.
Im going to be finish welding a bracket to hold the turbo this weekend and starting on the headers. Im excited!

twins only apply if you have a small displacement V8 that isnt very powerful N/A.... otherwise, a large single is better....
hmmm.. i donno.. seems obvious to me that the compressor housing is going to aim the boost into the cabin, where a air/water intercooler of some sort would cool the air and send it back thru the firewall to the now backwards intake.
of course, thats just a guess based off all the pics shown.... oh, and its how all the other LS1 fbodys do it...

It wasnt invented by the LS1 crowd. The mustang people started doing it first. It just makes sense. Its going into the passenger compartment to an intercooler where the passenger seat is.
The only thing in the way on the LS1 is the oil pressure sender and thats not a big priority for me anyway. Ill just tap in with a mechanical gauge anyway. Ive got that on my daily driver and it works just fine. lol

Frankly, thats crap.
Tell that to the people that are out there in their 10.5 tire mustangs with 347 inches running a single turbo and running mid to low 7's in the quarter.
Obviously, two will make more power than one but to say that one cannot feed a V8 is just flat wrong and has been proven time and again

Even though twins are more piping, its probably a lot easier getting two 3" pipes bent to fit around stuff than it is for a single 4".

i'll just say this:
Corky is a very opinionated individual.... lol

you've never tried it... have you? lol (not being mean, but our cars were designed with the exhaust as a afterthought.)

Not to mention that turbos now have come a long way since that book was written...Some of the stuff Ive seen releassed in the past couple of years is just nuts.
single 4" tubing is not hard to route...I routed mine fine...guido had his routed fine... and if you need to go above 4" thats what they make OVALIZED tubing for...

As far as single vs twins… a larger turbo tends to be more efficient, so as long as you can get one big enough for the application that will spool sufficiently quickly…

Still need to add some bracing to the main plate, but thats prety much how its going to be.
1 5/8" diameter chromoly vertically, 1" piece horizontally, and a 3/8" thick steel plate for the mount.

My 4" downpipe fits easily under the hood and in the car...In fact I have room to go with a bigger diameter downpipe if necessary... besides with twin 3" where on the DS can you go with that...with all the crap thats in the way on the DS Id just as soon route 1 4" pipe..

I will take a stab at that. He put it on backwards cause he is probably going to run a intercooler on the inside of the car. So if you look how the turbo is pointed the pipeing will go through the firewall through the intercooler and into the intake. So with the intake backwards it accually makes for less intercooler piping.

No actually the TB is pointing backwards because Guido wanted to compete in Front wheel drive class at the NOPI nats...the rules state must be front wheel drive and must have forward facing throttle body.. soooo he is turing the intake and the seats around and will be driving it backwards....

WOW ...that IS a big turbo
I am a newb at turbo's .....but I started off right ....went and got one :P . I read that book too. when I llok at the BSS kit I got ( application specific ) I think the sinlge is the way to go for me . I am running the TPI with mine so it negates the need for a turbo for the bottom end .....
I still have NO clue what I am going to do for my down pipe and wastegate emmissions ( I need the perfectly legal and streetable setup )
Very nice man ! I keep bumping into your name when I do searches

Damn Guido, I thought you sold that pile! J/k
And to all you single turbo non-believers:
My buddy just went 9.13 in the 1/4 with ONE single T-76
('90 mustang /351 windsor/ 850 DP/ T-76 / water injection (no intercooler) And we could only get it to 12.0:1 AFR watching the LM-1. I think I can get it into the 8's if I can lean it out to 12.8:1 or so.
That T-88 looks WAY bigger than my bud's turbo! Can't wait to see if complete!

I’ve got a holset HX40/H1E off of a freightliner wrecker (you know, the ones that they use to tow busses, loaded semis...), and an HX50 and HX55 off of an 11L and 14L Cummins stationary diesel… all are relatively small, physically. The 40 is about the size of something in the T60 range, the 50 and 55 are about the same as something in the T76-t88 range.
In most cases the HX50 and larger are from stationary diesels or serious heavy equipment, and I’m guessing that the really big holsets you’ve seen were like HT60’s or HX80 or 88’s (which are somewhere in the 80lb range)

The turbo i have was originally designed for deisel truck service and it had a 65mm inducer I believe. The wheel in it now is an 88mm inducer 116mm exducer. Its a hos. LOL
