http://www.drivesrt.com/news/2012/08/behind-the-scenes-with-gts-r-lead-engineer-matt-bejnarowicz.htmlQ: Instead of asking to be allowed to run the 8.0L Viper engine, would you ever ask to run a lower displacement 5.5L engine (perhaps a V8)?
A: LOL! That would just be wrong. In fact, that question has fairly offended me and I will ask that you don’t talk of it anymore.
That's a non-answer to me ... I don't accept that.drew54 said:To settle the V8 talks, from an interview last year with the lead engineer Matt Bejnarowicz

Not a problem for me ... and yes it is juicy.Muther said:The Viper will be a V10, until sometime beyond the end of time. I would estimate that the first Viper to NOT have a V10, will be the generation intro'd the model year AFTER the universe collapses in on itself in a reverse big bang. RG hisself said that Viper "will always have a V10". OK, so it will have a V10. Nobody said it had to be an 8.4 liter pushrod! A 3.6 liter V6 divided by 6 cylinders equals 0.6 liters per cylinder. 0.6L per cylinder times 10 cylinders equals a 6.0L V10. Hmmmmmmm?
Going further...
A 3.2 liter V6 divided by 6 cylinders equals 0.533 liters per cylinder. 0.533 liters per cylinder times 10 cylinders equals a 5.33 liter V10. Spawning a new Viper V10 engine from an existing V6 doesn't seem all that far fetched to me, and if the P-Star were to morph into a Viper powerplant its output per liter would go way way up. The way I see it, spawning a new Viper engine from a current engine, is right in line with Viper's history.
Is there any other place such a package could be used?
Maser'? Alfa?
What is the distance between the bore centers on the P-Star?
Or in other words, how long would a V10 version be? How much taller would it be? How heavy?
Sorry for the derail but this was too juicy to pass up.
Hey you guys did all the heavy lifting. I wanna thank you and hemi.magnum for the top notch coverage. Keep up the good work I cant wait for next year!moparbob said:I personally wish to thank all those members that joined in on this discussion this weekend, ESPECIALLY the new members & Viper fans that logged in & posted their thoughts with us. Your continued support & commentary for the Viper Program throughout the 2013 ALMS season is greatly appreciated & we hope to see more of your support as SRT now heads to Lime Rock for the next ALMS race!
Also, my deepest thanks to our ALMS head reporter & Allpar collegue, Hemi Magnum, (Ron Granados) for such great coverage & assistance with the race reports this weekend, also a big thanks for sticking with the race for nearly all 24 hours of the race.
Other thanks go out to reporters Mike V., SkyBlade, & Jeepnut for their additional supporting reports & pictures from LeMans. It is reporting like this that seperates Allpar.com from any other enthusiast forum on the internet! I only hope we can carry success & keep the interest of you, the reader & member like this into other forms of motorsport here on Allpar.com. We simply can't succeed without your involvment or taking the time to post here in this section!
Oficially we have broke a new Allpar record here in the Motorsports News Section as this thread now has at the time of this notice being written has recived 7606 views this weekend across two threads - 6646 views here (New Record) & 960 in Mopar News & Rumors and potentially still may climb into next week? This viewership total is higher than ANY of the individual NASCAR race coverage threads we had here through all of last year! It's so great to see how many enthusiasts & Chrysler race fans care & come together! This is a very proud moment & achievement here on Allpar.com, once again, if you viewed this thread this weekend, pat yourself on the back, for you have my sincere gratitude & thanks! Let keep this performance going into next week!
Sincerely,
MoparBob.
Yes, Javelin AMX, you are right. During Alejandro de Tomaso's reign at Maserati, he held a reception at the factory for dealers/distributors and friends of "the house" at around the 14th December each year. December 14th was the Birthday of Maserati.( l think l remember the date correctly)JavelinAMX said:Not a problem for me ... and yes it is juicy.
I'm in at least general agreement with you.
Displacement issues being what they are with the 8.0L ( homologating the Viper being the chief problem ), it seems the smart thing would be to investigate doing as you suggest - leveraging existing tech (the basics are already in their parts bins). A smaller displacement base engine could surprise the competition. Even if it yields just power on par, but reliably boosts fuel economy; it would aid pit strategies.
I really wanted to address what you said about a Pushrod V-configured engine.
Now with two other notable brands more or less In-house ( vis-a-vis' Ferrari and Maserati ), there are other options that could be explored. 4-valve per cylinder OHC is the obvious assumption; but historically there have been successful 5-valve designs; and 6-valve design that was tested, but not produced. Reference to Maserati above gives the in-house nod to their explorations from the 1980's ( http://www.maserati-alfieri.co.uk/alfieri26.htm ). Maserati never built them; sticking with 4-valves per hole. But the 6-valve Turbo'd prototype made 130 BHP per litre. With 5.5 L displacement, that's a bunch of HP (minus HP leeching from the extra cylinders and mechanicals of a V10). But it does give pause to consider competitiveness from a different viewpoint - not just an 8.0L Push-rod V10 .
Apparently the race rule regulators choked the viper into not being competitive. If only they allowed another 50hp.Mr.Source said:With those long straight we need speed, I thought this was going to be a Viper advantage, but it seems they are not fast enough, they will need to be very fast, corners are not very good for those Vipers, just hope they can do something to make them real fast and reliable.
Yet, Honda fielded an 8-valve Oval cylinder engine in a two-wheeler race series.Morty said:Yes, Javelin AMX, you are right.

And each year he had to show something special, most of which never went into production. l used to attend these meetings, and l remember being quite excited about the 6 valve head. That was until my good friend Sig Cozza, one of the old racing engineers from the 50s an 60s whispered in my ear that they
had experimented with 5 and 6 valve heads on the formula 1 engines they supplied to among others the Cooper f1 team - 3l V12 - but did not find any noticable gain from them. As to output per liter, the biturbo engine was sold in certain markets in Europe in 2L verson with 306 hp in standard tune! That should equate something like 153 hp per liter. (Just another piece of useless information for you)
You might recall some years ago the Hennessey Viper? Twin-Turbo 1000HP ?Muther said:Personally, I love the current Viper engine. I love its sound, I love the way it thumbs its nose at conventionality. Normally aspirated, i'd guess it still has another 50-100hp in it. I would also looooove to see a V10 version of the P-Star. 5.5 liters, 4v, DOHC, DI, done with the current firing pattern as the current engine (if possible) to retain the unique sound.
