I don't remember whose it is or what the name of the car was, I think you are right though. There was something about a guy named mike that I remember.
Yeah, its mike moran's. He's been making news all over the place for this motor. I've heard that they've had a lot of problems with the motor, its probably kind of difficult plumbing all of that and keeping all of the boost down, even with the waste gates.
That does not look like a 350 to me. That is insane but i wish i had an engine like that in my car. I bet the boost arives at 7000 rpm. There is such a thing as excess and that is it. Those turbos are each bigger than the average supercharger.

I have the August 2001 issue of PHR in front of me that has the article regarding the "Quad Turbo Monster'.
Theya sked him what the displacement of the engine was and his response was:
"...this is a GM DRCE-based turbo engine that'll rev almost 10,000 rpm - you figure it out." "So we said that's a giant bore, relatively short stroke, and a long rod." Meaney answered, "You're on the right path..."

its probably something around a 477 i believe. S.A.M. has a similar motor, its a 502 big block with a 454 crank i think revs to like 9000rpm
The SBC 427 engine was built last year. Normally aspirated and on pump gas it made 650hp/580tq, with 500+ ft lbs from 3000 to 7000 rpm. It's a pretty good motor. I really haven't added up the cost of every nut and bolt, but I'd estimate somewhere around $18k, that's just for parts and machine work. I built it, clearanced everything, and double checked clearances, etc myself. It could be built for around $10k by using more conventional parts without giving up too much performance. Things like the Hogan's aluminum sheetmetal manifold, Jesel belt drive, Crower Ultralight crank and billet rods, etc could be substituted for cheaper, yet equally effective parts.
Actually, the motor would have made more power and torque when we dynoed it, probably somewhere around 700hp and 600ft lbs, but the headers weren't ready yet so we were froced to use some 1 3/4 headers we had laying around. I ran 1 7/8" stepped to 2" headers when it was installed in the car.
To accomodate the TT system, I am lowering the compression from 11.27 to 8.5 and going with a shorter duration cam.
My strategy has always been to maximize efficiency, and turbo's are more efficient than superchargers. Of course packaging them is alot more complicated and more expensive, so all things considered, it's probably a trade-off. However, I just prefer turbo's because I should basically be able to drive around town and the engine should be relatively mild due to the shorter duration cam and the lower compression. Then when I need the power and the engine load increases, the turbo's will spool up and provide the power I need or want. That's something that alot of people seem to not understand - turbo's are not rpm dependant, but rather load dependant.
Also, since this is a street car, I wanted to maintain a stock appearance - 'the sleeper approach'. The body and interior have been restored to stock, so at idle and cruise rpms, there wouldn't be anyway for others to know what I've got without me raising the hood. If I had gone with a Roots style SC, it would be a dead give away, and centrifugal SC's tend to still make a little bit of a whirring sound at low engine speeds. Of course, once I get the turbo's spooled up, or the BOV's open up at high boost, some people may be able to figure out what's going on.
I'd get a nice security system for it. I also worry about that. I have had one car stole from me, got it back with minor damage and found the guy who stole
Thanks, I'm pretty proud of it. It's been an ongoing project for about 2 years now. I only put about 400 miles and 30 dyno pulls on the motor before deciding to do the twin turbo deal. I had planned to do it next year or so after I got more use out of the SBC 427, but I saw John Meaney's car on PHR TV one sunday morning on TNN (and saw it in PHR magazine), and ordered the turbo's and wastegates the next day. After seeing how much power he made, and how streetable it is, I was immediately sold on it.
I just spoke to Tom at TRZ Racecars this morning, he's the one building the headers, intercooler, and exhaust. He said it'll be doen this weekend. We just started on it last weekend. I spend the weekend down there helping him build the headers.
Once I get the car back this weekend or next week, I've got to pull the motor out and take the block, heads and rotating assembly back to Fast Times. They're gonna rehone the block for the new pistons and since the Dart block was brand new when we first built it, the bores have probably moved slightly. I'm replacing the exhaust valves with soem Del West Inconels, and the crank needs to be rebalanced for the new pistons. The turbo pistons are about 15 grams heavier than the current ones. I may o-ring the block, but I still haven't made up my mind yet.
I have heard that the best way to prevent your car from being stole is to get a gas shut off switch that must be pushed to start a eletric pump or open a feul line.
That would not ahve worked for me though. They pushed my car down the street and hide it in their garage. For some reason they start to take my engine apart =(
that was a long time ago and has not happened since.
Just hope no one else has to go therw that.
I wonder how your time will be, you thikn it will be close to 9 seconds (quarter mile)?
I have no idea what the car would do at the track, that's not really my goal. I'm trying to make it an all-around type car - something that I can drive on the street with good reliability, yet still run decent times at the 1/4 mile, yet still put a big grin on your face on a road course.
If you just look at the power and weight, it should run 8's, but I know that won't happen, and I don't think I even want to go that fast. Realistically, I'm hoping for low 10's. The problem is the rear differential. I'm still running the Corvette independent suspension, although I've upgraded it with forged yokes, spindles, and 1350 u-joints. I have to intentionally keep it traction limited to prevent it from breaking the rear diff. I'll probably just run Michelin Pilots or something like them - more of a 'road race' style tire than a slick.
sweet!! where did you get your sbc turbo manifolds?? hopefully I will be starting on my project turbo camaro soon, I plan to get some parts from ls1 motorsports (mostly the manifolds) and then go from there. YOUR CAR ROCKS!!!
:hail:

hahha thanks man!! its actually a drift, I was going in at about 45 mph and feignted the turn (no brake or ebrake). we have a driftsession every second saturday of the month here in hawaii. its so much fun!! they let us use part of the road course ... we get a s turn, a big burnout pad /skid pad area and a big 180 degree u turn. there are mostly imports there but last driftsession we had three 3rd gen's representing the domestics. i'm gonna try and get some video sometime!! revlimit (also a 3rdgen.org member) is a master drifter!! he was doing choku dori (sp?) down this 2 lane street and kept just missing the curb ... i was like WOAH!!! hahahha
Sorry to sound like an ***, but what is so big about drifting? You get to go around corners sideways and eat your tires off i about 2 laps. That doesnt sound very fun to me.
Give me something an inch off the ground, some 18" meats and Road Atlanta or Mid America... now THAT would be fun.

You don't sound like an ***. Drifting is basically a different type of style in racing, yes it eats tires, and yes it takes a lot more practice than typical grip style cornering. I look at it like this. If you can slide the corner @ a 45 degree angle and maintain control, when you grip you will know exactly what is happening when you are sliding and might be able to control your "slip" a little better. Each has its own advantages. In japan Drifting is looked upon as an art more than a racing style. The more powerful the car and the more graceful the slide looks the more points you receive. Seeing a 300ZX take a sweeping flat corner @ 75 MPH with the rear tires smoking @ a 45 degree angle is pretty impressive in my book.
I remember my most expensive smoke show. It was after school, the last week of being a senior. I did about a 6 minute burn out. When the crowd start to yell at me to do another I started to then I blew my tranny, and my rear end.
Peer pressure is a bitch
I'll never do that aain, well as long as someone else is telling me to.
