If you were going to build new track motor with 550 whp dry sump ..
Any specific things you would do or ask for?
Things to stay away from? Just curious .. Would like strong motor at least two seasons out if it..
Any specific builders?
This is a track car

Any specific class of racing? Location?

I just had a 615 fwhp with a 4 stage dry sump built by Nutter Racing Engines.

Forged 416 stroker. LS3 4.06 x 4.00 stroke. I used Trickflow 225 heads that I already had, but you could increase hp by using ported LS3 heads.

I had a special cam designed by Louis at LG Motorsports, .619/.619 lift. Definitely not good street manners.

On the engine dyno it had more than 520 ftlbs of torque starting at 3500 rpm, peaking at 580.

Motor builder told me to bring the dry sump pump for him to check after every season, but expected that I should get 6 seasons before major rebuild on the motor.

PM me if you want any more info.

A) how many races/seasons have you gotten so far, and
B) How much $

OCCOMSRAZOR

Brand new motor. Haven't even got it to the track yet. Hoping to put some time on it next month and run its first race at The Ridge, in Shelton, Washington. (I am also doing a major chassis rebuild so everything is taking longer...)

AC Nutter has been building race engine for more than 30 years. He also manufactures his own dry sump pumps at his shop in Vancouver, Wa.

My build was about $10k but I supplied the cam, injectors and heads. If you had AC supply those items and his ported heads, you would be between 12 and 13k.

You can find out info about AC at nutterracingengines.com

I always am intrigued with the number of seasons or years folks want on these motors that are tricked out.

6 seasons = how much time total on-track driving hard time? I'd take a guess at less than 75 hours and be.

OCCOMSRAZOR

I don't know what is so "tricked out.?" Top quality forged and balanced rotating assembly, ported heads, less than 12:1 compression running on pump gas.

It does not mean that I won't check oil for undo wear or evaluate the heads every year. I consider that to be preventative maintenance. What the builder was referring to was rebuild of the short block and rotating assembly.

For comparison purposes, a typical season for me is usually 12, 40 minute races (with the associated practice and qualifying sessions) two test and tune days, and a track day for my friends and sponsors.

This is a dedicated track car so it doesn't get driven on the street.

There is no guarantee, I just passed along the comments that the engine builder (who is familiar with my racing schedule) made for benefit of the OP.

You're experience may be different.

This sounds like an excellent road race, club racing motor. That is more torque than a Trans Am SB2 motor. (although they make a couple hundred more HP). Crazy torque, low rpm, pump gas........doesn't get much better.

OCCOMSRAZOR

You are correct. The engine builder and Louis at LG both knew my application and did a great job selecting components to match. However, the cam is really the key. I was interested more in torque than peak hp and the result was exactly what I asked for.

I really can't wait to get it on the track, although my fabricator and son suggest that I wear a pair of "depends" as they expect me to wet myself.

thank you looks like a good base line!

Tricked out simply means it has been built to get way too much power. There is always a price and trade for that. Now you've re-qualified that to the short block which may run awhile.

I am looking to build a strong motor that puts a good amount of power and torque.. and example to compare would be id rather have a good old labrador retriever than a wound up Greyhound .. both great dogs but in this world engines need to last... the M3 motor we had built is an estimated 100 hr motor with is reasonable..

I have a great car, Just don't want motor issues.. or at least keep them to a minimum

You have managed to seize on my underlying point with a great analogy.

Most folks only race maybe 6 times a year with OCCOMSRAZOR being the apparent exception. Even at that schedule, in 6 years (which the motor won't make without a LOT of "maintenance" the cost will run a minimum of $75/hr. .... just for the engine.

In reality, however, most of these "tricked out" engines will only run 50-75 hrs, hard, and the true cost will be more than $100/hr. Makes brake pads and tires suddenly "inexpensive". And unfortunately, you probably won't get around much, if any, faster with a 650 Hp engine than you will with a 450 Hp engine unless you are at the top of your class and driving to the limit as in 11/10ths.

I'd stick with the old lab and in the end have a winner and a lot more fun along the way.

<<<<<< Greyhounds are cooler than Labs, though.

Keep in mind there are no OLD Greyhounds still racing!!! But my old Lab is still hunting!!!!!!!!!! LOL! JD
