Yea thats what i heard too.... I have 4000 rev springs in it now..... Should i take it all the way to 4000 or just take it easy and go to 2500?

 

i'd say take it to 2500 or so for 1/2 - 3/4 of the mileage and then a little higher towards the end. and take it easy up there too, meaning low to no boost......

when we broke in a friend of mines gas engine (turbo 4) we eased it up to 4-5K and then left it in gear and let it engine break itself down to 1500-2k.... we made some soft pulls in 4th gear up to those rpms and then let off and let it slow back down. we did this for ~20-30 miles after he drove it for a week locally in town ~200-250 miles or so.... the theory is the vacuum it makes in the cyls helps seat the rings better. then after 500 miles or so we beat the living crap out of it..... then the head messed up and we had to change that but the bottom end is still good and tight. accually i'm going to get it and put it in my ranger soon..... the bottom end of the motor, forged flat-tops....mmmmmm

 

i guess we were hard on ours, when we finished my buddys turbo mustang we pulled it out in the street and did a 5K boosted launch . different strokes for different folks i guess. but all the old school engine builders ive talked to said check for leaks then drive the heck out of it.

either way, awesome truck, let us know the results man!!!

 

ya i've heard that too.... they say that you are prolonging the inevitable if you do an easy break in .....

 

that s a badass smoke cloud man

 

Looking REAL good Eric...

 

Yea, right now its my only running truck so its gonna get some miles put on it. Hopefully next week I will feel like I have enough miles on it to open her up and she what she can do. Gonna go take it for a drive, its so nice havin a 12v again, just raw power no electronics....Ahh thats nice.

 

glad ya had somethin ya could back up your 08 with.

 

Well that pump came in just in time i have only been waitin on it for a month.... Oh well at least i got the damn thing. Some kid in a ricer tried messin with me at lunch today and I "accidentally" but it to the floor..... i only let the revs hit 3500 before i shifted ..... Yea he didnt want to play anymore
