Towing With New Mods: Brief Review

[Puff]

Kurt Yardley (Kwikkurt) installed some modifications for me. Here’s a list of the mods and a brief review of my first towing experience with them:



Mods:



DDIIs

KS B-1 Turbo

SB OFE clutch

Comp Box

Lift pump replaced (Carter P4601 HP) and relocated

Stacks (stack pictures)



Towing:



- Outside temp ~35 degrees

- Elevation range 6500’-7300’

- I have a Mega Cannon air filter

- Towed from Albuquerque, NM to Farmington, NM and back (~160 miles each way).

- Trailer weight ~7K lb.

-

In 6th gear, with cruise control set at 70 mph, and comp on 3-3 I never hit 1200 degrees. When I hit a hill, most of the time it would hit 1100 and sit there as the boost increased. Boost on hills ranged from 20-37 psi. I hit 37 going up a very steep hill, but temp was still under 1200. I tried towing on 5-5 and it was fine -- boost built up faster and temp remained under 1200 on some pretty good hills – If I was towing more weight, I’m sure I couldn’t tow on 5-5, but for 7K lb. it was fine. Stack noise while towing in 6th gear was very loud until I got over 1900 rpm; I towed at 70 mph most of the time and that got the rpm up to 2000 and the noise was fine. Fuel pressure was very stable, ranging 9-13 psi.



This is a great combination for towing. The KS B-1 is a great turbo for towing!!!

So I'm guessing no muffler huh Puff? That's the ONLY way to do stacks!Oo.

Actually, I've got a BIG ass muffler on it.



I was disappointed at first because it is so quite when not towing -- thought I should have gone with a smaller muffler; but when towing, the noise increases a lot and I'm glad I have it.



I may put a different muffler on it though; if I do, I'll post on the difference in noise.

For guys that tow and have stacks and want to keep the noise down I have a solution.



Keep your original exhaust in place and install an exhaust cut out in line then hook your stacks up to that and when you tow you can reroute your exhaust back through your stock system.
