Thanks for the knid words, Some pictures(lots) from Silverstone last Sunday, it was my first event in this championship.
I broke a driveshaft in the warm up(had to strip my road car), only completing 1 lap, in the practice broke the front splitter.
Before the event looking at last years times I set a personal goal of 1min 10, in practice I did a 1:10.780, in the superbattle qualyfying I managed to improve to a 1:9.919, this was a long way of the front running Imprezas and Evos doing 1min1s and 2s.
I was 2nd placed front wheel drive car, just over 2 seconds behing an ex Touring car Honda integra DC5.
It was good fun and hopefully supprised a few people with our unusual Saab,s.....

I cut my chain with a dremel and jammed it up while trying to feed it out.
Had to remove the timing cover to fix my F-up, so then I put in Nick's blocking plate.

|Tweek's Turbos||Ok, so its on with just deleting the chain. I just had to order a spare dizzy cap blanking plate for the head, and am dropping off a con rod with a snapped and stretched studd to be replaced.|

Well, my first one I did it while I had the oil pan off to clean the pick-up screen... Just cut the chain with a dremal and pulled it out through the bottom with vice grips....

|crazybrightman||mine vibrates like mad with no balancer chains, lightened flywheel and lightened crank, then polly engine and gearbox mounts. infact its like a motorbike vibrating bolts undone sometimes! on a 2.0 id take them out but leave them in on a 2.3 unless you are going for lighter forged pistons then things maybe inproved slightly.|

|sleet||to me it doesnt seem really worth the hassle to take that out. i guess mine will stay.|

The balance chain guides and parts can fail and take the motor out!!! This will not be an issue with chain removed. Don't have to rebuild or spend money and time on that part of the engine anymore.
Cons: If you do not plug the balance chain tensioner hole, 20 buck part from Nick, you could have the balance chain tensioner blow its piston out and you could lose oil pressure.
The second biggest reason to not remove balance chain is the increased amount of vibration, why they are there to begin with, and with the 2.0 motor its not bad at all, but with a 2.3 motor, the vibration at idle is worse.
If vibration at idle bothers you, do not remove the chain! Once moving I can not notice any vibration issues, but they are there with my poly motor mounts and 2.3 motor at idle. Makes my mirrors buzz....

Ok, sorry, I was not sure if you knew the difference You are right and if you remove the shafts themselves, there is nothing to block the oil passeges and keep the oil pressure up.
Nick made some aluminum inserts, but the only advantage would weight and I personally don't think its worth the time and money and effort to save the 6-8 lbs or whatever they are...

|sleet||as some maybe aware im planning on maybe going bigger with the saab and i been thinking about the balance chain and considering doing awya with it or keeping it. now someone enlighten me but it seems less worry-some to just keep it all in and not mess with it really. could someone please give the pros and cons to keeping it in or taking it out|

There are tons of us that have removed the balance shaft chains... I have had mine out on both my saabs for over 2 years now. Nick now makes a tensioner plug that keeps the problem from occuring.
The issue was that on occasion, the balance chain tensioner would blow the piston out and then you would loose all oil pressure....
Kyankton did this on his new monster ng900, he just made a blocking plate for the tensioner hole, looked just like Nick's...
The nordic race cars uses a block with no balance chains at all..... The block was not designed for them...

|crazybrightman||it has a b206 block from an early n/a ng900 these had no balancer shafts from new so stronger and lighter block as far as i know. you have to tap out the feed for the oil squirters though as the n/a didnt need them so they werent fitted. oh and theres no return hole for the turbo in the block either.|

|Castor Troy||i seem to remember reading about somebody who simply removed the balance shafts, without putting a plug in. that is a recipe for disaster|
|05-28-2008 04:13 PM|
|Tweek's Turbos||"No balance shafts" was that a misprint? I think I remember yankton doing this, but caused the failure the first time around at soc05.|

ha is nice was looking round it the other day when picking my rebuilt viggen box up. keeps stripping the teeth on third gear and the engine brace to the bulkhead made a hole in the bulkhead! must be a beast lol.
nick makes sure you get them too him before july as i wana see how it performs on them before i make a decision on what springs rates i want.
|05-28-2008 11:30 AM|
|GenuineSaab||Yep I need to get Wessy a set of my springs.. He has been bugging me for a while on them.|
