Another phase II

alanoo

Well I know, first phase is not 100% finished, but it frees some time to start collecting parts for engine #2 😃

Teaser :

Came with another set of Eagle rods of course :mrgreen:

vocky

eagle crank 8)

whats the spec for your phase II ?

alanoo

Well, still not 100% defined and subject of many animated discussions with my best friend which is working with me on it..

Option 1 : ₁₂.7:1 CR
Option 2 : 9.5:1 CR

😉

vocky

sounds like my phase II, its forever changing :lol:

both options sound good to me 8)

blue_se2

Mad you are both mad!!

alanoo

Oh, just bought another small bits for the phase 2

As you bought a 2.0 saab engine, I assume this is a forged 2,2 Eagle crank??

vocky

can't wait to see this project evolve 8)

alanoo

Now at home

Misses the Saab coils, but all is there, the oil cooler, intake + exhaust manifolds, even the ion sensing ignition module
Oh and didn't realize that at first but as it is a E85 Biopower engine, should be much bigger injectors as usual :thumbup:

vocky

what a bargain 🙂

looks brand new, well I suppose it almost is :lol:

alanoo

Current probabilities are 60% for a Rotrex C30-94 setup, 40% for an ITB one 😃

exmantaa

Rotrex should fit nice in the AC comp. spot...

Has this E85 biopower engine different compression pistons than standard saab 9-3/LSJ??

alanoo

Nop, but I don't care, pistons will be changed as I will use the Eagle forged crank

alanoo

Ok, just decided I won't go for a supercharged solution

I may regret it, especially if there will be more than a few TVS powered VX220/Speedster on track in a few months but basically for the reliability level I want it implies having the block resleeved, a good clutch, a low pressure pump for feeding a swirl pot + a pot + an high pressure pump .... and a bigger fuel tank to have more than 5 laps of fuel on track, 4 pot brakes to stop this all and with that all doubts will starts with the gearbox reliability.... this never stops.

So engine 2 will be NA, again

(and if it lacks a few HP to keep with the TVS guys on track, there's always the NOS solution :lol: )

vocky

NOS, hmmm......

alanoo

More a joke than anything else, but could be fun...

vocky

I've always wondered whether it's a good idea or not, a nice 50 bhp shot of NOS would be quite nice :lol:

alanoo

The engine will support it with no issues, I'm just wondering how much the whole system weighs.

Won't the weighs will cancel the few tenth seconds gain of a 50 shot on track ?

Reminds me of the current "KERS/or not" discussions the F1 teams have at the moment :lol:

alanoo

Planned specs :

AT power ITBs
LSJ ported head
Full Schrick valvetrain (not yet 100% sure)
Eagle 2.2 L61 crank, lightened
LSJ 2.0 rods with ARP bolts
Clevite TriArmor rod bearings
Custom CP pistons with DLC pins (₈₇.50mm bore)
Ferrea valves + 3 angle seat job
Mechanical chain tensionner
Adjustable cam gears
Custom oil pump gears + lowered oil pressure
Exedy flywheel

or maybe a harrop TVS... :o

Estimated first start : autumn 2010

alanoo

Slowly moving
I bought one of these a few weeks ago :

So it will most likely start with a tuned plenum, and if tuned well there will be no ITBs

No LSJ rods too as these are shorter than L61 ones. Was led to believe the LSJ were longer reading some stuff from the US, but this was wrong. But Eagle ones will do the job perfectly, they are really a very good product for the price considering these are half chinese rods.

Next steps in 2010 🙂
