Im looking into getting a set of twins, for towing and wanted to know what you guys thought was the best set. 500-600HP range, 01 HO with 6 speed. Im in Colorado Springs so ATS is close, but havent heard that much about there twins. Have heard Piers is nice and not to far from them. any help would be great, thanks.

 

twins need more fuel.. so you'll need injectors and a fuel box there with that setup to get 500-600 HP.. Also you need tranny upgrads.. you if you go with ATS.. have that tranny word done too

 

piers makes a nice set if your alright with an internal wategate

 

I can tell from experience 600 with a stock HO pump is pretty much not going to happen. I've got 200+ hp injectors which with the stock HO pump only give 180 RWHP. I've got a tst comp that only gives +/- 90 RWHP. I've got 35/3b twins and 40/3b twins. Neither will get me close to 600 RWHP. My last dyno was 492 in 1:1 with 35" tires. I now have 33's and have done some minor tweaking. I'll still be lucky to brake 525RWHP. IMO just about any set up twins will work. It all depends on what you're willing to pay. I dont personally care for ATS so they wouldn't be MY first choice. If you willing to do some work youself Rip at sells a do it your self kit.

 

So would you recommend a hot rod VP 44 if looking to achieve 600hp

 

All depends on who you talk to. A lot of guys like there HRVP's. I personaly wont spend the money on one. I'm going to an SO once my HO dies. I may loose a little throttle response down low, but for the 800 dollare differance I can live with it. IMO a good cam can be had for around that price and should give me back the bottom end if all that is typed on the net is true

 

to get a cool 5-6 hundred horsepower, i would run a tst comp and a smarty along with mach 6's or 7's. But you need either a SO pump or a HRVP

Then throw on some BD twins and maybe a little water meth and you'll hit 550-600 easily. Thats how i would do it. But you've got to get rid of that HO pump!

 

PDR twins all the way.....

In your post it said twins for towing. If towing is something you do alot of, concentrate on the lower end of your range(500hp) instead of the upper range(600hp). Injectors and exhaust housings can be smaller and you'l have less heat and better bottom end power.

 

I agree, towing with 600hp is gonna be a pain if you tow heavy. If you stay around the 450 to 500hp mark it will make towing a little easier and you wont have to be watching your EGT gauge every 5 seconds.

I recommened the BD twins, they are very well engineered and the kit comes 100% complete with great directions.

With a SO pump, your egt's are going to be sky high running mach 6er's while running a box. I would go the B2/Hx-40 route for decent spool-ups and cool egt's. Running the BD twins the biggest injectors I would run would be around 180 injector size, you should be in the low 600 to hi 500's and have a nice daily driver. Your trailer might get covered in soot, but you can tow with those injectors. Mach 6er's are too messy to tow. I pull mine out and put in a 130rwhp size injector. No soot, no smoke, no egt's and it still spools the turbos fairly well.
