680whp? Please! He's making more than that. With the large Puerto Rican community in South Florida competing with the guys in PR, 680whp is not an accurate number. It's way too conservative. You have the 10sec Alltrac up here making that exact amount and running 10s. That Paseo's making around or over 1000hp. Factoring the power to weight, not even 680whp could get him near 6s. The guys at Hard Target are making more than 1000whp right now, and are not there yet. Close but not there yet. As for the use of MicroTech LTX12, versus running LTX8 on the 4cyl, it's simply because of the extra outputs. As good and reliable as the LTX8 is, it's lacking in extra options for hardcore racers, so some go for the LTX12. They are great systems though. And most of the 3S guys making all that power run the 5SFE block. Still impressive numbers. It makes me proud seeing a 3s powered car running these numbers.
