[Peugeot-L] Re: 505 V6 (prv) Twin Turbo

Don't doubt the lunacy associated with John Lane or his 3.0 liter, even-fire, turbocharged, PRV-powered Volvo Rally Car. It doesn't make the least bit of sense to invest in 600hp for a 2WD rally car when the greatest rally driver ever (Walter Rohrl) was barely able to put 2/3rds of that kind of grunt on the ground in what had to be the baddest 2WD rally car ever built (Grp B Opel Ascona 400), but you'd have to know John like those of us in the rally community do to appreciate the whole gig (John was whack enough to loan me his Nomex so I could run a Nissan Sentra SE-R in the 2003 Oregon Trail ProRally after UPS sent my box of racing gear to Portland, MAINE instead of leaving it on the left coast). John and I have a standing challenge to see who can outrun whom whenever I get my Peugeot 505 V6 Rally Car project completed. It's kind of a philisophical argument I plan to win despite a n/a engine to be put together from engine parts left-over from my 504-V6 sedan project of the 1980s and a skid full of parts purchased from John after he abandoned n/a PRV power for his Volvo. My engine will likely only crank out about a third the horsepower of John's 'fire breathing monster' but he needs to quit wrecking the Volvo every time he enters a rally and I need to sell the New Beetle Rally Car and quit letting myself be distracted by a Group 5 Omni GLH Turbo and the Cousin of RallyeTruck that I procurred recently.

Below find a little 'fire breathing monster' history as shared by John Lane's fabrication partner in crime, Dave Clark. BTW - I couldn't get any of the URLs to work ...

---Here's a picture of the most powerful Volvo-powered Volvo you will probably ever come across. It's a ProRally car that the owner, John Lane, and I built. It's a Volvo 262 that originally came with a 2.7 liter Peugeot-Renault-Volvo joint venture V-6. It now has a 3.0 liter engine with even fire heads. Lovely engines, all aluminum, fully skirted block, forged crank, etc. After winning his class in the NorPac Divisional Championship with it running on carburettors (and rolling it 3 times!) John decided he wanted more power. So we turbocharged it. J&E pistons, Garrett TO-4 turbo, HKS adjustable wastegate, SAAB 9000 intercooler (very efficient at low speeds), Electromotive TecII injection, 3 inch open exhaust, the works. We were very happily surprised when it ended up putting out over 650hp!

John tuned the Electromotive on a chassis dyno and the Fire Breathing Monster (as we call it) put down 504 ft/lbs of torque at 4000rpm at the rear wheels. That was at just 11psi boost, we've only run it as high as 14psi boost so it's really not stressed. In fact, the engine has been the most reliable part of the car. As you can imagine with that kind of power we started breaking everything behind the engine. To make a long story short we systematically beefed up the entire drivetrain. The car now sports a Quartermaster triple disc clutch and lightened flywheel, a Jerico 4-speed dogbox from a Winston Cup stock car, Ford 3/4 ton truck driveline and center bearing, and a Ford 9-inch rear end with Moser 35-spline axles (1.5 inch diameter!) and a spool with 3.50 ratio gears. The relatively high final drive ratio is to help reduce wheelspin. With that kind of torque there's no need for the 4.88's we used to run. For stopping the car now uses Porsche Brembo brakes all around. After a few failures of the stock front struts we have installed Ford Escort Cosworth Group A magnesium front hubs and Group A Bilstein 50mm coilover struts.

Is the car fast? Yes, it's totally gonzo nutso out of control stay off the sidewalks fast!

http://www.i-club.com/ubb-files/eek.gif Top speed of 143mph across the I-90 floating bridge at 3:00 a.m. (as recorded by the Terratrip rally computer reading off a front wheel probe.) Not bad for an un-aerodynamic Volvo brick. Cruising at 60mph you are right at the threshold of boost. Floor the throttle in 4th gear at 60mph and there's no lag. If it's even a little wet out the rear wheels will spin - there better not be any cars next to you on the freeway! If it's dry you will just launch into the back of the car in front of you. It's fun to play with rice boy Hondas on the freeway, or better yet, Porsche 911 Turbos. They don't expect a Volvo to be that fast.

Do you really need all that power in a 2wd rally car? Absolutely not, it's totally ridiculous, over the top and unnecessary. But it sure is fun when you can put the power down! Often times John will just turn the boost way down if the conditions are too slippery. It may be over the top but there's no greater rush than spraying big rooster tails of gravel sideways down a logging road!
