Matt was making upwards of 400...


15psi, iirc and a fuly built 4.2. he tried running some N2O....once


also, an M112 car recently made 460 on blow and 576 with spray

 

Correct, I sold my built 4.2 with a blower set up to buy my truck.

When it was at it's best, it was mid 500s and designed to run corners. 85% of my build is suspension/brakes. The rest was aero and working on power to weight ratio.
Up front I ran tubular K member and A arms, Steeda x2 balljoints, 1050lb springs (about twice as stiff as typical lowering street springs), revalved Bilsteins, Roush sway bar, Engery Suspension bushings, Flaming River steering etc... Rear sits on Roush tubular control arms (have South Side Machine boxed LCAs that are adjustable that I swap in sometimes), stock UCA, GT sway, 650lb springs, revalved Bilsteins. Brakes are Roush calipers, SS lines, Hawk pads, Baer 13" drilled / slotted up front and out back.

Def not something that hooks from a dig, but coming into a hard braking corner I can lift a passanger out of the seat and let them hang in the harness.

Right now it's a basically stock 3.8L under the hood. I've been working on a better port job of my M112 and going to the 2.8" pulley again. Power to weight is still pretty fun for a street car right now.

 

So you've been doing more M112 work and testing on your car?? And thats a crazy spring rate, when I talked to MM they recommended me 250-300 I believe it was for my dd. 15psi...wow

 

I'm working on getting more flow out of the blower without having to pay for a Steg or other high end port job. Between that and trying to work out the 4.0L set up, I've been quietly busy.

 

thats cool man. do you make any money autocrossing? or is it just for fun?

 

you lose money auto-xing, it's not a paying gig by any means.

 

An open track weekend will cost you entry fees, gas, hotel, at least one or two sets of pads, maybe a set of front rotors, maybe a set of tires and anything you might happen to break on the car.

 

Not bad Matt. It's not too shabby of a price either but you still need a lot of stuff to get it running.

Have you looked at the work Posi on SVTP does? It's a pretty decent price and they seem to be giving pretty good results.

 

I haven't cruised SVTP for awhile. I'll have to check it out.

The guys at C and M sell it as a complete basic kit. The down side is it's set up for stock fuel system. More fuel and less pulley could go a long way on the 4.0L.

 

What are the stock internals on the 4.0 normally safe up to?
