Sample Simulations
 

I came up with these dyno curves and some software simulation drag times you might find interesting. TT = the stock dyno graph in the October 2001 Turbo mag article. T78 is the dyno graph from the same article. t04e is from the xs-engineering web site and the t04s is from the same web site. The 350tt is from a member that has a highly modded stock twin turbo with a 350RWHP peak. Myt04e is the estimated dyno sheet with my mods. Dave at KDR and Tri at XS-Engineering say this is about what I can expect. Please remember the software simulation is used for a relative comparision of one to another. Everything is optimum so the times are unrealistically good.

What I have learned is that low end power is very important for the beginning of a drag race. After that you are always above 4.5k rpms.

Very interesting info you shared with the forum. Thanks for posting this all up.

I have to write down all this info down soon.
