Henri Toivonen Lancia Delta S4

ok, en(dot)wikipedia(dot)org/wiki/Lancia_Delta_S4 It has 550HP so stop arguing.

i'am not trying to argue i'am just pointing out correct info. Anyone can add to Wikipedia so its not a reliable source. Alot of figures for group B cars are alot higher than what they actually are.

Wikipedia IS a reliable source because you have to post references and links to where you got the info. If you don't post that Wikipedia will take down the article. If you don't believe me go to the bottom of the article and go to External links and notes.

Hear you go Mac, I made an S4 video just for you youtube-com/watch?v=h4R9swgqGjU

Using that same argument, did you research the external link? If you did, you'd know that the 550 number was submitted by an individual who shows no connection to the race team nor to the production of the vehicle. Information, no matter the source, is only as good as your ability to interpret it. Since Marv has more corroborating sources then the Wiki article, which is a restatement of a submission of an individual who got his information from who-knows-where, his information is more reliable.

Yeah, I did go to the external links. It has 550-600HP depending on boost. End of story. Don't bother replying because I ain't got time for replying to the same shit.

The two external links, one is a picture gallery and the other is a tribute web page; second-hand undocumented information. Marv's information is still far superior to anything you've provided. I'm not saying you're wrong, just you're being fooling in assuming what someone posts on a Wiki is fact. But I'm going to shut-up now and listen to some old advice, "Never argue with an idiot; they'll bring you down to their level and beat you with experience every time."

Marv's info isn't more accurate. The guy first said 480HP then 470 and said only that the car had a turbocharger. The car had both a turbocharger and supercharger.

you see, the thing is that when the lancia was introduced, she was realy a 470 hp. but as the time was goes by, the engine was upgraded to about 550-600hp. so, you are both right =)

...mixture in the cyliner head and thus enabled higher compression ratios and higher boost pressure to be used. Which could get the S4 up to a max of 470bhp.
