theres so many different oil pump options out there im wondering what real time feed back is, so post up your experience with the pump youve got and pumps you had previously.

im currently looking at the ported ls6 pump from TSP, hence the question.

I was going to do the ported ls6 from tsp but ended up going with the Melling high volume. havnt got the motor in my truck to see how it does.

ported LS6, holds 38-40psi @ idle and when I am on it she'll go right to 60.

Slp pump and slp double roller set. I initially had low pressure spring installed and just this week installed high pressure since figure my 408 is fairly loosely setup and can use a bit more pressure. So will see how it does a few weeks when start driving car around again. Slp makes it much easier to run a double roller chain and at my power levels I wanted a double roller.

TSP ported ls6 pump with a rollmaster double. 40 psi hot idle, 80 psi at 6,000rpms no problems to speek of. When I built my new moter it pirmed right up (3-4 sec of cranking the engine over) haven't thought about it since. Are you having problems with your pump?

Has anyone had a stock oil pump blow up on them? I had 2 oil pump failures. The first one the pressure relief got stuck open. The second one actually blew up and broke the housing and all the teeth off the rotor. I'm running a katech pump now and have had no problems. I have a melling high volume for my 370 going together now.

Why does everyone think they need a HV oil pump. They simply are not needed in 95% of all applications you will run into on here. Plenty of guys in the low nines running a stock pump or LS6. This is the main reason I went with a Katech ported LS6. The same reasoning applies to single versus double for timing chains. The C5R chain is a proven piece. A double will break just as easily as a single given one weak link. I honestly get so frustrated at some peoples reasoning for doing what they do.....

Here is the problem, there is no proof that a factory tolerance motor regardless of power, needs a high volume or high pressure oil pump. Funny how many aftermarket companies that have been heavily involved in the GEN III program, run anything but a HV oil pump. Katech being a great example of this. The problem is everyone thinks more is better, so HV pump=more protection. This isn't always so. And often times not needed.

i have a turbo motor, so my clearances are more on the loose side then the factory specs.

also a HV oil pump will not cause damage, even to a stock motor, yes it is not necessary, but will not hurt.

I agree it will not cause any damage. For the record I never said it would. Its simply not needed for most applications. I can think of several guys here in close to 1000hp that are not using the HV oil pump. And these are FI cars. Whatever makes you feel good.

i agree with you there, but im also thinkin of the guys running twin turbos. theyre bleeding off all that high pressure oil before it ever even hits the motor and without a HV pump how do you know if your good enough? if and when you find out your not, its already too late, pulling the motor to replace all the bearings sucks ***.

for the record, my current oil pump is 12 years old, Is the original 1998 ls1 pump, and has just over 140k miles on it. Now im putting a turbo on the car and bleeding off a little oil, and since i have to pull all the covers anyway, im replacing it for peace of mind.

I run the ported and blueprinted Katech oil pump, as well as the C5R timing chain. If theyve never broken one in endurance road racing, hen im sure itll hold up to me driving to work

i just use stock pumps, port them myself, add a small spacer under the spring
i also make sure its installed right, ck the clearances all around

I'm running a stock volume/pressure Melling pump on my TT setup. Wanted to keep the seals on the turbos happy.

iTrader: (11)

Heres the thing, a turbo really isnt going to add much bleed off to the system. If you are worried install a shim and bump the pressure up 10psi and be done with it. Again plenty of ultra high HP cars I know of running stock pressures and only porting (LS6) without any failures. Hard to argue with that. But again if it makes people sleep well at night get a HV. I am going with what KATECH recommended, their ported and blueprinted LS6 and I might shim it, but probably not as I dont think its needed.They are one of the few companies who are true experts on what works in the GEN III motors.

^^^ im going with the ported ls6 pump from TSP, seems like a little more volume/pressure than what ive got, without being overkill.
