Roush Opinions On Upgrading 2000 Saleen SC

Rob,

I've got a 2000 coupe, series I, actually bought it at Downs Ford down in Toms River. I'm from up north tho, Bergen county.

Had it on a dyno- stock with the Chicane RIPP, ran 306 HP 355 TQ. It was real rich up top with that stock tune.

Recently had some stuff put on- Chicane Pump, 42 lb injectors, 90 MM, Densecharger Meter Forward, SCT tune. I am scheduled for the Dyno tomorrow at 2pm- i'll post my results in the forum.

Mine dynoed 278rwhp /343rwtq.
After blower swapp 433rwhp/419rwtq.

No comment.

I do a blower swap. Kenne Belle. Save you time and stress.

Because of the Series I’s inefficiencies, I would do all the port work and Series V inlet first, along with sealing the gaps between the heat exchanger in the manifold. I know some people have changed out the front mounted intercooler but have never seen before/after data posted.


Of course, full power will be realized with all the modifications performed but if you add the smaller pulley before the porting and heat exchanger work, the blower will make more heat than power. Even with a good tune, the motor will still be subjected to high intake charge temperatures and additional stress.

I don’t hear anyone talk about this these days but the biggest gear recommended for a Series I on a manual transmission car used to be 3.55. Again, this has to do with poor blower efficiency and its power band in relation to gearing. If the port work is done before or at the same time as the gear change, you will probably experience more favorable results.

I pretty much have the same plan as you do but have not committed to dropping so much money into trying to maximize power from the Series I. For this car, I want to keep the Saleen blower intact. Good luck with your mods. I am looking forward to reading about your progress. If you can, dyno the car with air/fuel checked and if possible, find out what your stock intake charge temps are.

Save for motor, upgrade fuel system and then Kenne Bell 14psi kit.

With the kenne bell your number s would be 400/400 or more. A guy has a 1.7L Kb on here and he makes 433rwhp on a stock motor with a safe tune. And once you biuld your motor, 500-600RWHp is possible when u up the boost.

anytime you push that kind of power (400+rwhp) on a stock short block, you're taking a chance. the most i've ever seen on a KB 1.7L was 464rwhp and about the same on rwtq. that's with a built motor, cams, etc. the 1.7L simply runs out of giddy'up and maxes out it's potential. 464 on a KB though is up there, you would destroy most any centri blower set up.
