Best MB V8 engine? or other

[french]

If you want a light V8 ( around the same weight as a 1300 escort engine)which revs & goes then a AJP V8 4.2 /4.5 are hard to beat, very linear power delivery. In a its home environment fitted in a Cerbera it hits 100mph @ approx 8secs so go lighter & well off ya go!!

Bare in mind the tyre sizes you're going to need to get the power to the road if you go the V8 route, especially if you are not going to have much in the way of an aero package.

Take a look at this Pistonheads thread.

I like the suggestion on page 2 of an Audi A8 engine with built-in transaxle, great for a mid engined car

SPX: Agree logically... but V6s just don't have the same attitude as a V8!

I’m more thinking about the size of the brakes you’d need having a V8 in a kit car; the kinetic energy will be off the scale!

Jimmy De Ville made a tuned up Volvo classic family saloon car engine into a 700 ish HP monster

I always had a soft spot for the Yamaha built all alloy 60 degree V8 the B8444S
as used by the Noble M600 developing some 600 horsepower with the aid of 2 turbos.

here's one I tweaked earlier. https://www.autoblog.com/2013/12/09/volvo-polestar-v8-supercars

These are the sorts of cars you'll need if you want a V8 that can get it's power/torque to the ground. If you want to build something smaller or at the smaller end of the scale consider something OTHER than a V8 unless you are comfortable detuning it.

Brakes are not a huge problem in light cars and even if it gets heavy there is a brake package right off the shelf for your needs.

I whole heartedly agree, seen the Can ams and Gruop Cs at the Silverstone classic and the Le Mans Classic more recently, awesome events.... these kind of cars are absolutely up my street.

 

[WDB124066]

Once you have seen a McLaren M8 at full noise [and that does not include the haybail run at Goodwood] driven by somebody who knows how to drive, you NEVER forget.

It took Dr. Porsche himself to assemble a team of hand picked Engineers working directly for him to make a car to beat them. Fastest circuit race car ever made.

Anyway 500 to 550 HP is typicaly what a F5000 5.0 litre pushrod Lucas FI dry sump 1970's era V8 will produce. They do not make much downforce at all despite the huge looking wing. If you decide you would like this much power in a small single seater take a look at the tyre sizes used by the F5000 to get that power to the ground.
They are very careful on the gas exiting slower corners not to spin right round such is the torque...

KIWIS READY TO CELEBRATE F5000 CATEGORY MILESTONE IN US THIS MONTH



Passports have been updated, work leave arranged and bags packed; now all the 14 SAS Autoparts MSC NZ F5000 Tasman Cup Revival Series drivers heading to the United States for the 50th Anniversary celebrations of their category this and early next week have to do is wait for the day they are due to fly out.



The long awaited US 50th anniversary celebrations are being held in conjunction with the annual Rolex Monterey Motorsports Reunion meetings at the recently renamed WeatherTech Raceway Laguna Seca in northern California.



The ‘main event’ is over the August 25/26 weekend. But in honour of their anniversary celebration year – and the fact that car owner/drivers from around the world have shipped their cars to the US for the occasion - the organisers have also given the F5000 category a spot on the programme at the ‘Pre-Reunion’ meeting the weekend before (Aug 18-19).



Because long-time series sponsor MSC (Mediterranean Shipping Company) regularly moves the New Zealand-based F5000 cars to and from events around the world, their owner/drivers are used to the process.



This time though series spokesperson Glenn Richards says the last minute waiting is proving a little bit harder…...



“Honestly, and I know it’s not just me, because I’ve talked to most of the other guys (about this) over the last month, we are all like little kids again, counting down the days – or the sleeps if you like – until we get on the plane.”



The stock block 5.0 litre wings-and-slicks Formula 5000 category is one of a number selected to feature at the annual Rolex Monterey Motorsports meetings. It is the only one, this year, however to be celebrating a major anniversary, its 50th.



“It’s a pretty significant number for any race category, when we think about it, and just goes to show, “ says Richards, “how good the original idea (of combining what at the time were state-of-the-art chassis with simple, cost-effective ‘stock block’ V8 engines) actually was.”



Joining Glenn Richards and his Lola T400 on the Kiwi squad at both meetings will be current SAS Autoparts MSC series champ Andy Higgins (Lola T332), former title holders Brett Wills (Lola T330), Steve Ross (McRae GM1) and Ken Smith (Lola T332), father and son Peter (McRae GM1) and Aaron (Talon MR1A) Burson, Michael Collins (McRae GM1), Dave Arrowsmith (Lotus 70), Russell Greer and Tony Galbraith (both Lola T332), Grant Martin (Talon MR1A), Frank Karl (McLaren M10B) and Tim Rush (McLaren M22).



UK-based SAS Autoparts MSC Series regular Greg Thornton (Chevron B24) is also entered, as are Australians Paul Zazryn and Adrian Ackhurst (both Lola T332), Phillip Lewis (Matich A 50), Bill Hemming (Elfin MR8), Frank Harris and Dean Camm (both Chevron B24).



At least 41 genuine, period-correct Formula 5000c are set to line up for the Pre-Reunion meeting next weekend (Aug 18-19) and as many as 47 at the main Rolex Reunion meeting which starts on Wednesday August 22 and finishes on Sunday August 26.



Heading the ‘home’ contingent will be the class winners at the recent second round in this year’s US Formula 5000 50th Anniversary Racing Series, Craig Bennett (Class B 1972-1976 Shadow DN6) and Mark Harmer (Class A/Pre 1972 Surtees TS5). Also entered at both meetings and expected to do well are former US F5000 Racing Series class title holders Seb Coppola (Class A Lola T192), Jim Stengel (Class B McRae GM1) and Rick Parsons (Class B Lola T332).



Regular New Zealand visitor Jay Esterer from Canada is also doing both meetings in his Class B McRae GM1. While joining legendary Kiwi Ken Smith as one of only two first timers still racing F5000 cars four decades after they originally did is American series regular (and former NZ series guest) Eric Haga – driving the very same car he did in period, a 1970 model Class A Lola T190.



When they are not preparing and/or racing their F5000 cars members of the SAS Autoparts/MSC NZ F5000 Tasman Cup Revival Series group will be able to check out the annual Pebble Beach Concours d’Elegance classic car event at nearby Pebble Beach, Monterey.



The annual classic car event starts on Tuesday August 21 and runs in parallel with the Rolex Monterey Motorsports Reunion until Sunday August 26.



The SAS Autoparts MSC NZ F5000 Tasman Cup Revival Series is organised and run with the support of sponsors SAS Autoparts, MSC, NZ Express Transport, Bonney's Specialised Bulk Transport, Mobil Lubricants, Pacifica, Avon Tyres, Webdesign and Exide Batteries.



You can follow the series on Facebook at F5000 New Zealand or on the NZ F5000 Association's website www.F5000.co.nz

Watch those V8's, try a V6 like Lee says...

 

[Stratman]

It's interesting to compare this (and the two linked videos afterwards) with an F1 onboard lap. The F1s get on the power the millisecond they pass the apex, the Can-Am and F5000 drivers wait until they're pointing in a straight line on the exit kerbs before opening the taps, presumably to avoid getting a 3D view of where they've just been.

 

[WDB124066]

Yes one has lower torque and downforce the other has higher torque and not a whole lot of downforce, that's what I was trying to get accross to anybody doing a lightweight home build sports car, V8's are great but you are going to need some serious tyres to stop spinning, so to go faster 4 and 6 cylinders make more sense from a weight savings point of view. Was it the Lola 4 cylinder T290 series of cars that hasseled the M8's, two completely different pholosophies, bit like Pontiac TransAm meets Mini, you just can't stop laughing, most entertaining racing going really.
