You can't have too much proper science and engineering.

There are still too many areas of car tuning which rely on hear say, e.g. tyres and brakes, or dam right lies, such as that electric super charger on here a week or two ago.

Exactly.

No substitute for proper research and understanding. Saves being sold lemons.

^ Valid point but once you've established airflow required, DR's and ve stuff you will soon drop onto a suitable turbo or be in the ball park fairly quickly.

There comes a point when you realise that to much technical stuff makes no difference especially once you start to think about cams, dynamic compressions and a whole load of adiabatic (sic) stuff which may or may no work. You have no way of knowing if you're getting the best package.

I've done those sites before and done my head in on the calcs. Some of them I won't visit again, lol. The buick site iirc is one to certainly do your head in.

I've decided to keep it simple, well simple/ish. smile KISS rules imo.

ETA, did he do these figures (site below), if so absolutely top man. I'd have given up long ago and settled for GT35 or GT37's. They leap out at you for this package as everything else is just so wrong. God knows why the yanks have been so far behind for all these years.

Ill take that as a recommendation for large displacement Natural Aspiration

boosted is right.

so many people have spent sooo much time, energy and money messing around to create the perfect combo.

Keep it simple...lots of HP needs lots of air & fuel. if you want 500rwkw then do some homework as to who has made these numbers and work from there...is it worth giving yourself a migrane over?

These engines are fairly forgiving and I'd rather not do 732 hours of advanced algebra for a net gain of 4 bhp.

In the length of time it took the guy to type all that...you could have performed a turbo build and had it up and running lol....


Also..his fuel system is a bit mental. No need at all for 2 of those Aeromotive pumps for his goals. One would have done.

He's put in a lot of research....but far too much IMO. Keep things simple.....

With a 408 that he intends, it would be a doddle to meet his power goals

the 2 Aeromotive pumps are for when he upgrades to the 2000hp kit.

Therefore LSX 454 with Fi =

I have spent all evening working that out.

Roger and I did the same independantly, then compared notes and agreed on a game plan.
Then found the best package and bespoked it.
You really do need to have a little science when choosing and making your own turbo system.

So what nitrous system are you going with Jez to firm up the response? hehe

Perhaps, but when there are so many tried and tested setups out there.....its easy to pick a setup that will perform.

Now where is the fun in that!?

Its always good to "know" you have the setup you think you should have rather than some random one.
Maybe 9 times out of 10 you would have picked the same one, but at least you "know" its the right one and can spout some geeky facts and figures to back it up.

Which is what we have done...basically.

With your girly cam and low compression you might Are you running a 440? or 427?

Spoke to Mark at Rapid today, he is finishing of a twin turbo 454 in a vxr8. There is going to be some mental stuff about. The strip is going to get pretty torn up later in the year.

427 mate.
Sounds like there`s some good stuff coming, hope we see it all as we don`t often get to see much of the stuff Mark does for some reason.
