IIRC, Maptun quote the Stage 3 at 265 HP. The Stage 3 is listed as the ECU, Exhaust, Intake combination.bwell said:How much of a BHP increase would I see if I up graded from my stock 900 turbo.
I running about 270 bhp MapTun stage three ?
Is there any other benefits
Well there are a number of more or less bolt-on units that outperforms the Viggen IC by a mile.Rogozhin said:What intercooler would you suggest pade?
here we go again...fromero said:I wouldn't say I agree with the above. Intercooler design and manufacture is key to good performance. These $100 bucks IC are usually a piece of crap, bad welds, restrictive to airflow, inconsistent under pressure/temp combination.
The "art" of designing a good IC has to do with calculus of debit of air in and out (no restrictions, but neither is interesting to have such a big IC that pressure drops) temperature drops at different presuures, and else.
The majority of IC's adapted to Saab's are usually wishfull thinkig, the reality is it has to be well calculated for your pressure and air debit you are working with, except for exotic performances, I would say the only one I know to be of a good craftmanship and calculations is the Forge IC, although I have no close knowledge of the ETS, which looks like more or less the same, but we should know if its restricictive to flow or pressure.
Just my own 2 cents, and my personal opinion and experience. :cheesy:
I guess the "art" of "guesstimation" is as good as a method as testing without an IC tester...ETS Michael said:We are in the process of building an intercooler tester
Bell intercoolers said:What ranges of efficiency can be expected from an intercooler?
A typical air-to-air intercooler for a street application achieves between 60% and 70% efficiency, an excellent/optimum design for road racing can approach close to 90% efficiency, but requires an adequate "budget!”
it depends if you're looking for a "plug&play" solution or not. There are many units which will fit with modest work, when the size is kept resonable. If thats not enough, then you will need to spend a few more hours in the garage to modife the surrounding parts to make room for the bigger IC.fromero said:Now where do you say these IC's for a 93 can be found of a relative size so as to repalce the stock Viggen one?

Even on a stock Viggen it does not work efficiently enough. You MIGHT see a few horsepower gain in a quick dyno sweep on your setup but in real life on the street when you are pulling through the gears in a long WOT-run, intake temps will skyrocket with the Viggen IC and your car will quickly be out of breath.
If you are upgrading the IC, get something that works right away and don't mess about with a toy for a IC like the Viggen unit.
