I was talking to bollman last night and was saying how I really wanted to see how high I could get my HP and torque, simply fantisizing about things. He stated that I would have to watch out due to the thin walls of a T7. I then begun to wonder, at what point would the T7 engine block start to break? I began to research this and found that the pikes peak viggen has 750 HP and is boosting 42 PSI on a T7 engine! what are the limits to a T7 engine and how can you make them higher, other than better pistons of course.

Ive been wondering where would you get highperformance pistons for a saab capitable of handling almost 4 baRS OF BOOST!!

I guess you are not the first one to wonder about it ..

I remember like three years ago .. I had the opportunity to meet a Manager in the Saab regional office for the Middle East.. who worked for Saab for like 25 years..

We were having a discussion about tuning and such stuff .. then the Pikes peak car came into my mind .. so I asked him about it .. specially that It produces 3.5Bars of BOOST :!: on the 2.0 .. he smiled and gave me the following statements:

- One piston of the pikes peak car engine costs around $8000 :shock:

- The pistons and rings plus some other engine internals are disposed after every race

I guess you can imagine the rest :mrgreen:

HOLY SHIT $8000 a piston. that comes to like $32,000 just for freakin pistons !!!!!!!! I hate to be a saab hater but you could build a kick ass engine for 32,000,, I know you guys are going to hate me but, mabey a twin-turbo LS1 650Hp reliably would be more worth it. the whole kit cost only $25,000 and it will probally last you longer as long as you are not going too crazy. Just look at the stress levels. 650hp/8cly................750hp/4cyl huh mabey thats why they cost sooo much. :lol:

400HP 9-3 Daily Driver http://maptun.com/cars.php?id=55

330HP 9-5 http://maptun.com/cars.php?id=46

450HP NG900 http://maptun.com/cars.php?id=56

400HP NG900 http://maptun.com/cars.php?id=63

These are just some of the higher Hp cars out there running T7's making serious HP and being daily driven. The block on a 9-3 from my research is not a bad block nor is the 2.3 from the 9-5 Aero. So if you start with those motors and spend 10K on forged pistons and rods, balanced cranks, etc...... you can probably get a motor that can rev to 7K or so and put down 500HP with good ECU tuning. Those SAAB's are out there you just have to want to put the money down for the results.

Nice, :) Do you know when a stock 9-3 hits the rev limiter? I was looking at this one guys saab on cardomain and I he took a pic of the turbo gauge and the needle was totally in the red with just a ecu upgrade, wouldn't you worry about the turbo shaft warping at temps like that?

The stock turbo's (TD04 Aero Turbo's) are rated to handle around 330HP or so if you get up past that you need to move to a ball bearing turbo like the gt28 or GT30 and that will do the heat and the HP you want. As for the revlimiter it gts adjusted with the ECU tune so you don't redline until 6500 to 7000Rpm's or so. A stage 1 ECU will get you buried into the RED zone of the stock boost gauge easily and will almost break your guage if yo get the Stage 2,3 or 4 ECU's. On a stage 2 or 3 you should be looking at 16PSI or so on a good 3rd gear pull!!
