Top teams in all kinds of racing are always a lot faster than the slowest cars in their class. They can all buy the same components and do. The difference is all the knowledge developed and attention to detail. My engines have been tops for a number of years but it wasn't always that way.

|NDNslicks4me||I bet one thing was to polish the pistons and run more compression with the same boost compared to the other guys for starters, that could be an easy 50 HP right there in itself. But 100 HP is a lot....|

There are literally hundreds of "tricks" some good, some bad. The tricl is to know what one you let them do to yours

|lowROLLERchevy||93 octane in the 950hp viper, 93 octane in the vehical it was compared too|

would be easy as long as you didnt hafta run pump gas, you never mentioned the fuel being used.

|gilby246||This is very possible!! I know cause I did it and will tell you how....ready?? I used a tornado, K&N Air filter, fuel line magnet to atomize the fuel better and an electric bilge blower..ssshhh, donít tell anyone though.. I would prove it to you but I sold it cause it had to much power and scared me.. I was 16 at the time so go figure|

I know nothing about Viper engines. That said I have built numerous drag race engines, mostly Chevy and Ford, big block and small block.
A blue printed engine carefully put together with uniform clearances will make more power by reducing friction losses.
Carefully blue printed oil and water pumps can reduce the amount of horse power needed to run them. By carefully running as light weight valve train components as you can find and reducing the tension of valve springs as much as you can will also reduce frictional drag.
Careful polishing and shaping of crankshaft counterweights and the use of a windage tray will reduce drag on the crank.
The scientific use of coatings can also gain small amounts of horsepower.
This is just a small sample of the possibilities.
Each technique by itself won't gain much but done together as a package will easily gain 10% or even more.

when we raced a world challenge viper in 2000. with a a back door factory sponsership we laid 560 horse power to the rear wheels.. N/A! thru a restrictor.

fine, let me narrow this down some
lets replace "stock" in some of those spots with "as commonly available from their aftermarket mfg's"
a "stock paxton supercharger" would threfore become "the paxton supercharger that you can buy from paxton, without any mods done to the kit"
Poncho, the extra 100hp is compared to similar builds, a viper that someone threw aftermarket pistons and rods in ... basicly situations where people ordered the "commonly available" upgrade parts, w/o realy looking into if they were "perfect" for the application.
mosstrooper- i doubt i have to explain how 1000hp out of a v10 viper and 1000hp out of an engine thats less then 1/2 the size are 2 VERY different things
and i decided to call Jim Oddy performace (yes that jim oddy)

100 HP more...................So, that means that a stock Viper v10 puts out 850 HP?
Starting to see the ......
|02-23-2007 01:29 PM|
The definition of "Stock" is pretty loose. I build allot of NHRA/IHRA Stock eliminator engines. We use all "Stock" parts too.
Then again doesn't everyones "Stock" '70 340 Dusters run high 10's in the quarter?
I'm not saying he's BS'n everyone, maybe he has found some major design flaw that he's corrected. However 100hp with just a short block and no cam change is a head scratcher.
|02-23-2007 01:17 PM|
This Laddie should introduce himself the the Formula One Teams, they run about 1000HP too, but spend countless millions getting there.
Oh! and one thing more, they only last 2 races and then need a half milion rebuild.

say you have a THOUSAND horsepower engine..... (technical engine question inside)
ok, this has turned into a huge debate over on our local car forum ...
a local guy is a Viper specialist. he has poured a TON of money into building his car, and seams to be well on his way of offering a very good number of self designed performance parts
a while back, he built a short block for a customer, and he built it totaly to his own specs. hes staying mum on what he did, which is understandable is a niche market like the vipers are
recently, the engine was finaly dynoed in the customer car and compared to similar setups in other vipers, it made almost an extra 100hp
everyone is trying to cry B.S. on this, that its all dyno error or that the results were "fluffed" .... what do you engine experts think ? is a 9% improvement possible out of the short block alone ?
