How do I get to the 400hp range

[Menes06GT]

Ok so IDK if this is in the right section or if i'm gunna get flammed for this but i want to know. Im gunna be building up the car for raceing now that im leaning off the show sceen and I'm looking to bump up the power from the 310RWHP/325RWT to somewhere between the 350-400hp range with highter tourqe then hp(more realistly im guessing 360hpish) but I wanna stay N/A and i don't wanna have to mess with the bottem end(pistons, crank, ect) Is this even possible? Im already on a 91race octane tune with a CAI, UDP, CMDP, catless mid pipe and some axle backs. I was thinking getting some long tubes, some cams, so 3:73's and maybe somthing with the fuel system(bigger injectors or fuel rails) would get me to my goal along with a good dyno tune but idk. Is anyone out there pushing these kind of numbers or could give me sugestions on how i could gould get there?

Sell your car and get a 5.0--Better handling for racing and you're already at your power goal from the start.

More power, I get that. But better handling?? I thought the 5.0 cars were heavier and had the same basic suspension?

 

[TheKurgan]

Throw some hot rod cams in and be done with it. That will get you close to 350. To go to 400 NA is going to be extremely costly.

Going NA I dout will ever see more torque than HP (cammed), not on a 3v at least.

New 5.0 with brembo pack is on par with new m3's.

I thought that was basically springs, shocks and tires? All of which can be done to the older s197 cars?

Am I missing something?

 

[fdjizm]

Yea the price it will cost for all those parts + installation lol

 

[jmauld]

I do my own installation, so that's a non-issue. I'm asking if there are any other hardware changes that make the newer cars handle better?

 

[Godzirra]

Supposed z brace that makes coyotes 12% stiffer. And few other tweaks that could still probably be done on 3 valves. I also think balance of the car is better.

Menes, curious what your plan is with the Cali emissions.

Im kind of in the same boat as you. Want to maximize my NA potential without touching crank.

If your looking to go all out in maximizing NA hp, you would def want long tubes + cams + heads

im looking into getting BBR stage 1s.

The extra 100 HP at the flywheel the new 5.0 has over the 4.6, which is very costly to get in a 4.6 3V naturally aspirated.

Before modifying the car for more power, you might want to decide what type of racing you want to do and what the class rules allow.

To get more than 350 HP at the wheels usually requires internal engine mods such as ported heads, cams, valve springs, maybe larger valves, etc.... Also, you may want to modify the car for the most power in the RPM range you'll be using instead of just peak numbers.

My car has most of the bolt ons available, except the FRPP intake manifold, along with mild NSR cams and I'm making just shy of 350 HP at the wheels. With a better tune the car might make a little over 350 WHP. I coudl add the FRPP intake manifold, but I'd lose some power in the 4500-6000 RPM range that I find useful on the road courses. You need to decide what your goals are before modifying your car for racing.

The difference is shocks, springs, sway bars. Same chassis, control arms, Kmember, mounting points, geometry. Boss has better diff as well.

^^This 'bold' above. Awesome statement and beat me to it. Got to know where you are going first!

As mentioned you will need alot of money to make it 400rwhp na. Matt D has a great thread with all the stuff he has done including his massive weight reduction.

You would be better off buying a small supercharger and only boosting a small amount to get you the hp you desire.

 

[kevinatfms]

i make 358rwhp and have added the following:
FRPP stock valve ported heads
127200 cams/UD pullies
BBK TB/CMCV deletes/tune
90mm steeda intake w/ tube
LT's/offroad h/gt500 mufflers
steel 1 pcs driveshaft
aluminum flywheel
3.73's

im pretty sure my numbers are on the low end of the heads/cams spectrum but with the hardware i have i just dont see me breaking 360rwhp without bigger cams or an intake manifold...
i would say to get closer to 400rwhp you def need ported heads and larger than 127200 cams as im basically maxed out on mine. with bigger cams and a C&L intake manifold i would hope i may be able to get within a testicle hair of 400rwhp.

A LSx motor would get you a n/a 400whp easily with just bolt ons and its a much smaller package but with equivalent weight (450 lbs) to the modular motor. I know .. ford forum and all but... The smaller 5.3l vortec can be purchased for under $1000, LS1 (5.7l) is about $1000, LS2 (6.0l) is about $2000. These motors a are all fairly interchangeable when it comes to heads, cam, plenum etc and even the smaller vortec motors can make good power. Only downside would be you would have to run custom gauges and a standalone ecu. You would probably want to run the t56 transmission (ls1 transmission). Off the cuff I'd guess the swap would be about $2k to get the engine the way you want, $500 for transmission, another $3k for mounts, cross member, ecu, gauges, misc stuff. Discount that by $1500 if you sell your stock 4.6 and tr3650 transmission.
