They say it cannot be done - 1000bhp Supercharged VXR8
Discussion
If I can get 680fwhp naturally aspirated with no effort then I dont see why you cant get a bit more with a little boost.
In fact it would be so easy it would be hard not to achieve IMO.
Most failures have been exactly that. Failures, and for good reason. Little to no research and little to no understanding of things. You dont use NA parts if you want decent boost. Heads lift, liners crack, gaskets leak etc. Ive pointed this out most vociferiously for years only to be told I was being negative.
Actually realistic might be more appropriate, given the woeful history of tradgedies that have befallen those who simply boosted standard NA engines only to watch them die.
Take a look at ERL blocks or the Dart LS Next line up. Looks like 3L+ Twin Screw is the answer. And use a cam that does more than build heat of compression against closed valves while you are at it.

And for the record, 'they' is reference to a bunch of people on the HSV forum that said:
(1) a 2.9 whipple was too big for a stock LS1 (the original thread that got hijacked)
(2) a stock LSA is good for up to 800hp on pump gas, but was probably only daily on a bit less than that
(3) it's remarkably easy to destroy your way through several engines before you get a working motor
There was also a lot of taking the p**s type banter that led to unfriendly responses all round.

And for the record, there's only been two UK based HSV/Monaros with four figure outputs. One is Harry's yellow Monaro that just topped1000hp and my red Monaro that made 1200hp. The best of the supercharged motors made 800hp IIRC. Normally aspirated cars run to about 600hp.
There have been lots of builds and lots of heartache. Everybody who's tried it has something worthwhile to say, even if it's be careful.
My approach was about as simple as it gets. I bought a fully assembled LSX427 for £8000. Bought some BW S300 turbos and had the lot fabricated up by John Sleath. It made 1200hp with ease (thanks to John's amazing tuning skills). The same engine now runs mid-8s on 97-Ron and must be pushing 1500hp.
So it can be done. I say go for it, cause you never know it might just work.

And as I said, it's a piece of piss to make 1000hp with the correct parts/tuning. And also said that level with the likes of a Whipple is just a bit pointless for a road car. Unless it's for towing 40ft trailers.(1) a 2.9 whipple was too big for a stock LS1 (the original thread that got hijacked)

Tbf NRE build 1500+ bhp engines for daily drivers and they love an LS block. Will be interesting to see how this develops.
I tried running my 1200hp Monaro as a daily driver and it was rubbish. Absolutely only fun to be had was boasting about the output down the pub. Unless you have an excellent 4wd setup, you simply cannot ever use the power. It's not just the speed limit problem, that much power puts you on the limit of crashing if you misjudge even slightly what's going on.ArnieVXR said:

yeha but how quick can you do the 1/4 mile, which is surely the domain of such a beast?To be honest, the thread title was clickbait
Please can we keep any more talk about what happened out of here and just concentrate on the build. Yes, there are no "pictures of shiny bits" yet, of course not. I am still spec'ing it all out. Also mentioned previously was this is a long term project that will go through certain stages and will take about 2 years to complete, maybe shorter, maybe longer, depending on my day job (currently 3 hours commuting each day )

I think if you wanted Clickbait you should have gone more along the lines of "OMG! check out this 1000bhp car build! You won't BELIEVE number 8!!"Please can we keep any more talk about what happened out of here and just concentrate on the build. Yes, there are no "pictures of shiny bits" yet, of course not.

I can confirm this as you took me for a drive in it. Anything other than idle would shred tyres, but not go any faster. As you say 100% pointless.But I take Stevie's point that with the right ECU to sort out boost control, traction, fault domains, torque control, throttle management etc you can "detune" it enough to run nicely.

Get 1000bhp from your V8 with this one weird trick! Engine tuners hate him!SonicShadow said:

Any reason for going with a whipe as opposed to say vortec YSI or Procharger F-1A? Both of these blowers should easily get you to your 1000bhp goal. I'm not sure if many have pushed the Whipple that high on reasonable comp. ratios and with normal fuel.
I like the way PD blowers deliver their power. There are plenty of examples of Whipples running 1000+bhp, shouldn't really be too hard Gassing Station | Readers' Cars | Top of Page | What's New | My Stuff
