Very nice car mate Cool

If your thinking of building a monster SD1 then maybe consider a 5.5??

And i have some nice WIIIDE split rim alloys that i MIGHT sell if your interested?

Anyway,that car is a credit to you mate,its really nice Cool

Thanks..

Thanks for offer, but i dont need wheels.. I like my compomotive´s..

Yes i know this 5,5 stroker crank.. But i just wondering is the rod ratio suitable for long life engine/good power? I think this 3,779inch (96mm) stroke crank need chevy 5,7"inc (144,8mm) rods and piston comp height is about 1.05 inch(26,7mm) Witch means 1,5-1,51 rod ratio?
And what i have read/hear the rod ratio should be about 1,7 or 1,8?
Or what are think about rod ratio? Is it matter?

Maybe you can ring us and speak with the boss or our main engine builder for the answer to these questions as i am still learning myself Laughing

Afetr 22 years experience,I am sure they can answer all questions,give advice on any performance upgrade you are thinking of etc etc.

What ignition upgrades do you have by the way?

The ringink maybe a proplem.. Very Happy

I don´t speak very good english, easier wrote than speak.. Very Happy

+ very expensive phone bill.. (Finland to England)

I run std dissy with bosch red coil. And no proplem at all.. Gives a good spark vs std lucas coil Shocked

Ok

After looking into the 5.5 theory for you,i have found that the 5.5 uses a different crank.

The Big End journals are a smaller diameter to give the longer stroke.

Your car would be much better with Mallory Unilite,A&R Power amp and Magnecor leads.
Gives much better spark Wink

Yes i know that there is a different crank. And i also know where to buy this crank. And this crank i can use std chevy rods, without machining a rod width. Also chevy 2" (inch) bearings are suitable.

Hmm you speak that mallory + etc parts are better? Off course you are salesman.. Laughing

I like std dizzy.. be enough to me.

Im not a salesman Wink

That is the Boss who is Laughing

I just say that if you use a std dizzy with std amp? then your spark output is limited,if you use std dizzy with high output amp then your gettin a much better spark Wink

And of course high quality HT leads Wink

Not trying to sell you,just letting you know Wink

Anyways,lovely car,do you plan on ever bringing it over to the uk to show?? Very Happy

You should be able to run 380bhp from a 5.3 Wink

330bhp from a 4.6 will be a big push though Confused

Are you thinking of getting the carbon fibre trumpets from us??

I just talk some e-mail converstation to Lisa.. Embarassed

I ask price with this aluminium 45mm trumpets base price is 250+150 without exchange Laughing

I think i still use my own setup.. Thats lot of money.. Very Happy

Not that mutch power anyway.
I order still (tomorrow send a fax) oil pump base + gears. Razz

(If my home build 4,6 "stage 3" valve head + std guides, with std 38mm trumpets, std 65mm throttle, std sd1 exchaust, std 3,9 ecu/ fuel (run very lean) faulty fuel pump pressure drops 0,5bar @ full throttle gives 280hp@5000rpm /440Nm@3800rm) I think it gives near ~300hp now with 45mm home made trumpets, good fuel pump, mappaple ecu + 4-1 exchaust and 72mm throttle.
I hope to get someday in dyno again ( when change the faulty oil pump base + gears)
I think near 330 is not a proplem with right parts and stage 4 valves.) Laughing

Will see, hope this summer or at least next summer. Rolling Eyes

(if i need a pockeded pistons?)

Yeah,they are expensive.

Did you say that you had been speaking with me online?
You should have told me that you need/wanted the oil pump parts,may have got a little off? Confused

I notice your plenum chamber is very unique,did you make it yourself and how do you find it has improved performance?
Also you have no airflow meter??

No i didn´t say that i speak with you in online..
I just send fax with RPI/Lisa. You can still spoke with Lisa to give me a good price. Laughing

Say healthy for Timo H from Finland (kokkolanpoika is my e-mail) Hope Lisa remember me..

This plenum, yes i make it my own hands, 3 minut practise of aluminium welding and then i weld it up. Very Happy

And it is not yet in place, because my oil pump/base is faulty and i have got very pusy at work. Also i need to make 2nd throttle gable system, and also to buy air filter + some adjustment to fit this 2nd air filter.
I dont need airflow meter because my fuel system is adjustable.. And i have got MAP sensor.

Rover v8, thought this might interest you, includes information (and purchase) of 'Trumpetless' bases (simular to TVR 500) and Plenum systems.

Thanks..
I have read this side sometime ago.
I´m not sure is this "trumpetless" bases good idea? Because inlet manifold trackts are now very different lenght. Shocked

I also have thinking to make this trumpetless base, but never be bothered to do it.. Very Happy
