3800 SC Exhaust System - Headers anyone?... I need another 20-40 HP!! (Page 4/4)

Would your tires allow you to leave harder? Someone already mentioned the 3.69 gearset change, what about a higher stall torque converter?

Without getting serious there isn't too much more to gain on the SC (think heads + bigger cam like XPZ).

The intercooler and dropping a bit on the pulley might help, but I don't think its a very effective return on investment.

Are you completely adverse to putting a turbo on?

I agree & logic tells me that going to a lower ratio gear would help launch harder and get that long amount of time spent in 3rd gear at a higher RPM. I found an old thread (attached below) and several PFF members chimed in that it wont help much due to the L67 long broad torque curve.

Anyone have any experience to dispute the contents of the above thread?

More goode thoughts and ideas - much apprediated, keep em coming!!

Three main reasons I don't want to turbo it.
1. Cost, the goal of this car since I built it 8+ years ago has been to go pretty darn fast for low $$$ Thus the name "DimeMachine"...
2. Turbo opens the door to 500+ hp. There used to be a chain available that allowed the 4t65E HD (with other upgrades) to handle this kind of HP. Now I believe that chain is no longer available and so 400WHP is about all the tranny can be build to handle. Kind of a waste to go Turbo if you can only barely get into the turbo's potential.
3. I love the instant torque the M90 gives the 3800 with the stock converter anytime you punch it at the stop light.

How much does it weight with you in it? Lighter weight = acceleration. Look for ways to make it lighter.
My Fiero weights 2350+ with me in it and it makes 304WHP and accelerates pretty fast.
You should look into making it lighter instead of making it more powerful! Just a thought!

I don't know but have seen people who seem to know state that the gen V supercharger is superior to a ported gen III. If so, they shouldn't be that hard to find since I've got two of them.

That particular engine is in my primary show car. I am not really into drag racing and have enough invested in this restored 88 Mera that it is unlikely to make a timed quarter mile run.

This is another 88 Mera project car that I might consider running a quarter mile after the engine is tuned. The exterior is ugly but paint will eventually cure that.
