Hey guys
I am currently running the BD Super B Special turbo and I am wanting to keep it and upgrade to twins...What twin setup could I go with that will perform good down low and up high and fuel enough for up to 650hp???...Give me some pointers...thanks

 

S480 would make a good primary with plenty of air to get to 650+.

 

Why not go with the BD set up? Their larger kit uses the Super B Special and being its a direct bolt in it would probably be the cheapest and easiest way to go. Check the website.

 

The S475 will make 750hp with your BD turbo ,You might not need a s480 unless you wont more power.I got mine from bullseye power 231 788 5209 with there twin turbo pipeing kit for $2999. Towing is very good and power is unreal you can smoke the wheels at 50 mph if you wont . Good luck

 

The special is what I run up top in the 850s. If you wanted to use BD you could upgrade the the R700s (though they come with the super B they are available with the special, pre request) or just step up to the 850s. With the mods in my sig the low end it great, and the top end pulls like an animal.

 

I know the R-700's rock. They tow incredible and have great street manners and rock at the track. Good for 700+HP. I know the R-850's are awsome, and make great power, i just don't know how streetable for everyday driving they are or towing. I hear they are super bad a@#. I know the R-700 are awsome, so I would say the R-850 are x2 that. Call Pat, talk to him, but it looks like you have the mods for them....Hmmmmmmmm

 

yup the r850 kit would be good for you, your special with a custom s400.

 

wat do you think the upgrade to the BD r850 would cost me??

 

The 850s are very driveable around town, at least with my mods they are, and thats on a stock cp3.

I really really like this set. I know there are sets that spool faster, and sets that make more hp, but these have excelent street manners and even with a stock cp3 and 2.5s I can burry a 60lb guage, and after that I dont know what my other gauges are doin cause im concentrating on road. I will get away from you in a hurry if your not carefull, and even with dual 35s I have to be careful on wet pavement when the big turbo lights.

 

call BD and ask for dave.bd performance my guess 2500
