Good thinking...

That's good to hear
i had a 3 inch single for a little bit on my car with open dumps and it still killed a lot of the power, however, i feel like 2.5 true duals would be sufficient till over 600+ as well...
dynojets cant be altered, thats why they are great for comparison.
have fun with the car now!!

lowers the coolant temps 10+ degrees after rompin gon it a few times
Wow, trefling congrats.. I been up to SGP Twice.. SC install/dyno, then UTEC install/pulley upgrade/dyno.. Mark is a genious, sometimes I think he needs to expand because there may be a little too much on his plate.. SGP is a great shop/great customer service as a whole! Hope to make one more trip there..... and move on....

So if he (Mark) turned it down what psi/whp will you be running on the street?

UPDATE 1/28/2007
dyno chart (left) on low boost, around 10 hp under 600rwhp. Mark say he tuned this to to 14psi but I have not seen anything over 13psi on my boost guage,
The chart on the right is at high boost, the drift/drag dual exedy carbon clutch takes some time to break in, the dip you see is the cluth slipping before grabbing again, just a hair under 650rwhp on PUMP GAS!!

I"m not sure if my Autometer guage is correct or not but right now I"m only seeing 13psi on the low boost setting. Mark told me he left it on low boost untill I get my second fuel pump. He said the dyno chart that is just a hair under 600 is the low boost setting. He tuned the car up to 18psi on 93 octane. The HKS 1000cc injectors allowed him to push further than you normally could with just the Walbro 255. I"m not sure at this point if I even want to try the high boost setting because it's so cold here, all I do is spin the tires. I was on the highway today in 6th and downshifted quick to 4th and punched it and the tires broke loose fast, pretty intense.
Low boost TQ (13-15psi)is 556rwtq at 3700rpm (dyno-pack, I'll get dynojet #'s soon)
High boost TQ (18psi)is 636rwtq at 3800rpm
Its' hard to see the #'s but the TQ figures but you should be able to see them on the dyno sharts on left of page
Later this spring I'll get some bigger downpipes, dual exaust & hopefully some wicked new plenum and push a little past 700rwhp. What really impressed me the most is how much power Mark (SGP) can pull with just 93 octane but he did tell me I would need some C-16 anthing past 650rwhp
Just one more thing. Last week when I made this post Mark told me that he made 598rwTQ, but the dyno chart (high boost) I have from him clearly shows the TQ to spike well over 600. Just wanted to point that out before someone calls BS
Id like to know the TQ as well
