are there any circuit figures of a few power variables for comparison anywhere?
I wouldnt want to waste money on power that couldnt be used effectively...

I'll shortly be able to show how a 497bhp (flywheel estimate) engine fairs against a 550bhp (est flywheel), in the same car round the same track. If it is only 0.5 secs. I'll be a bit peaved!!

and if its slower?
that happened to a guy i know who went from ZZR1100 carbd to hayabusa injected in our radicals. He ended up having to add aload of stuff to eventually make the extra power pay off.

all jokes aside if you could keep us informed it will be a good indicator, (but it takes a big man to be totally honest.)

A built LS7 will work out cheaper than £14K New LS7 block Callies internals, Manley pistons, Trick flow heads, Custom comp cam, fast intake, 92mm throttle body (cable) ECU and harness (programable) all ancilleries and a clutch lookingh around £8500-£10K to your door!!!!

One thing I do have in abundance

Only trouble is that I've gone back to a set of std G50 ratios (much shorter 4th and 5th), so I know already that Rivit (pelling?)straight will not be the bogged down drag that it was last year. So we have to somehow factor that in to the equation.

Oh I just found a new Engine at Amerspeed

There is a 725hp Version of the LS-7 now And I think the price is nice, maybe THAT could be my Engine Choice for the CanAm Has anyone some Informations About the 725hp LS-7? I wonder that the displacement is the same (7 Litre) as the standard LS-7 Version of the Engine. I hope a 725hp Version with the same displacement is as reliable / stable than the smaller LS-7 Versions? Have they use better Materials for pistons and crank to support the additional power? Or has such Engines a shorter lifetime than the smaller Versions of the LS-7? The 565hp Version is only 2800$ cheaper than the 725hp Version. 2800$ is not many money for 160hp additional! So is there any reason for me to take the 565 / 650 hp Version instead of the 725hp Version? Which LS7 would you prefer if you would buy an engine for the Ultima now?

Trick Flow cathedral port heads flow nowhere near the LS7 units. They do not offer a LS7 style port.
Our 725 + hp LS7 has stock displacement, Upgraded internals.

be great to get some feedback when your ready...what circuit by the way?

its a bugga on changing parameters - last night i weighed myself and put on a stonne!!!!!!!! back to the gym.

Snetterton.

The only circuit I can say that I've driven to the limit of my ability. Therfore a perfect benchmark.

When are you at Snett next?

Fancy sharing Sean Edwards for the day?

[craig7l]

snet 1:08.10 in a Div1 superkart if anyone gives a cr@p..hehe

when you going as wouldnt mind a look at a car around a circuit?

[Fat Arnie]

I don't know what all the fuss is about. The guy on that LS7 dyno video above is raving 1.7 hp/ci, whereas a tuned eurobox engine like this www.the-webbs.com/k2rum/k2dyno.htm can do 2.48 hp/ci. And that little 2.1 litre engine didn't cost £25k either, despite its BTTC pretentions. Even a very mildy tuned (carbs/cams/no internal mods) version of the xe can do 1.7 hp/ci.

Seems yank motors fall into the same territory as their cart suspension.

What does a fully dressed LS7 weigh in at?

[deadscoob]

How long can those tuned euro engines run at that hp ratio before needing a refresh?

That LS7 runs a similar ratio to Zonda F, F1, Enzo, CGT. So by your statement they're all pretty crappy too....

[Scotty-Boy]

Do you still have K2RUM Arnie?

Hallo Sebastian,

I am bulding a GTR in Germany (seems it will never be finished).
Regarding TÜV and registration you can contact Sven Schimmelpfennig (sveschi), www.ultimacars.de.
Where are you located. I live in the Pfalz, near Mannheim / Ludwigshafen.

And does it with pushrods and 2 valves per cylinder. Big engines are good at torque production unlike typical n/a 4 pots which have to rev to get anywhere. That said, ls7's rev to 7k anyway which seems like plenty for a 7.0.

Hello ultimichael

Nice to meet someony german who build a ultima

I had mail contact with Sven Schimmelpfennig He didn't answer my last mail, I think I should send the mail again, maybe he forget it.

I live between Münster and Osnabrück.

Can you send me your Email / ICQ / Skype or whatever? My email is [e-mail]. It would be nice if I could get a few Informations form a german guy, my english is not so good Please contact me, if you want

How much is ls7 though, seems like just the block? What happened to the light ls7 crank, ultra light Titanium rods, ls7 heads with Titanium valves and retainers etc, ls7 intake assembly, factory reflashed E38 pcm etc? To be an ls7 in my opinion it has to retain the main ingredients as those were the parts which made this an awesome engine in the first place.

Getting FT out the way first Rusty, but then it's on to a late summer of tracking, so yeah, Craig, Rusty, I'll be back on track just as soon as FT is behind us.

....engine willing.

[LuckyP]

I could be persuaded to take a half day from Sean. Be he tought me so much last time that I just need to practise it all before I forget....

...now what was it? Ah yes, mirror, signal, manouver!!!

Must say reading this thread is like a religous arguement!

I am not sure where the cost for these LS7's is comming from, I can see you need some specific Ultima related stuff, but £25K is having a laugh...

I was looking at an LS7 engine for my car, and all in I was being quoted some £8K for the engine/loom/ECU/sump/etc...

Power wise, in terms of BHP/Litre, they are still very low compared to Euro/Jap stuff but that's somewhat an accademic argument unless your racing in a fixed CC format or the like, the only real issue with running a 7L engine is the torque issues with the drivetrain over a simmilar BHP'ed higher reving engine (with correspondingly less torque)..

[SlackBlevens]

I'd love to know where you could get a turnkey LS7 for only £8000 when a crate engine is $13000 plus shipping, import tax & VAT. Then you'd need to add ecu, loom, front end bits, air-con compressor, etc.
