How to make 400 - 500 RWHP - 6.0L

[03 tx pwr stroke]

I made 436hp sotck injectors running 5" turbo back, S&B intake, no limit cold side and gearhead srlx... Hoping to have php ficm this spring And a mad hybrid turbo. Wanna see how much the stock injectors will do

Were these the ONLY mods you had? everything else stock? I'm having pretty much the same thing done right now minus the cold side pipe and was curious as to the power.

All the mods I have we're studs, no limit cold side, S&B intake 5" straight pipe, blue spring and srlxx

Just finished reading this entire thread. There's alot of great topics on power combos and what not, but nothing on reliability. You guys making power, especially at the 500whp mark, what kind of issues have you run into if any? And what kind of mileage have you put on your trucks since the mods were done? The local shop to me has been seeing a few cracked heads lately, anybody run into that?

 

[Blackblaze427]

Anybody?

 

[Jeremyleggett07]

That's prob a no

 

[bboteler]

my guess is most guys at this hp mark...think im close but will know for sure in May, have replaced heads and studs...heads are known to crack at stock hp due to the other issues. If heads were cracking here due to hp it would be much more talk about it esp as guys got to the 600-700 hp mark.

Yah that's what I'm starting to believe. I've been reading through this sit like crazy and haven't read a single thing about it.

There have been some guys with cracked heads, but as previously stated, that stems from other issues. One of these issues being guys putting on a big tune and driving it like they stole it without monitoring things like EGT, Coolant temp, oil temp, etc. get an insight with an EGT probe ( or other monitoring device) and watch it. I've been up to 1800* on some tunes with stock injectors. Now I'm around the 500 mark on Eric's XtremeX and maxing out around 1400* on the same stock injectors. It's all in the tuning and how you drive and maintain. Throw a Bullydog on and don't monitor anything while driving like a 16yr old tryong to impress his buddies and you'll have problems. Get some good custom tunes ( all PSA sponsering tuners have what you need) and some good monitoring equipment like an Edge Insight and you'll be fine.

Awesome thanks for all the input guys.

I thought there was no benefit by gojg. With a stock nozzle on even larger injectors!?

Ask Jesse warren..... These are smokey bi***es.... They add power trust me..... Lol this is a very fun setup the larger nozzle does help yes. Anything over a 175 the stock nozzle hinders you at least that's what I have been told but I could be wrong

Just curious as to what the power numbers would be for this setup.... Fully Bulletproofed and deleted, custom 5inch straight pipe, AFE CAI, TSD SPD tune with early lockup, ATLAS 40 FICM tune, 03 swap with batmowheel, stock sticks??? This is my current setup. Next is suncoast rebuild/converter and 175's or 190's

Laid down 530hp on a dyno. Had 13.6 @ 7740lbs with an exhaust. Never got a chance to run it at the track with all the leaks fixed and a full fuel system.
Mods, 175/0 powermax riff raff billet wheel, adp rr, a1000,
