I know that I am "shooting myself in the foot" with these good recommendations, but with a twin turbo set-up I am sure I will have "plenty of feet to shoot". Laust - what pressure do you plan to use on the Jalpa motor? I would think no more than around 9-10 psi without water injection. And are you using sequential small turbos for smooth pick-up? You can do pretty well with a properly sized single turbo, but the more rpm range you have to cover, the more a single will be a compromise at one extreme or the other, and if you plan to run it to 7000 rpm or more, I can see where a twin set up might work better. I use a single turbo on my street car with 13.5 psi, but only 8.5 compression, and it works out pretty well. Having seen what you did to the Espada, I"m sure the results on the Jalpa should be interesting! If you can"t get more than 350 bhp, there"s something wrong! And that sort of power in the Jalpa will wake it right up! Bill
