With a good dynotune stock Cobra 39's would be a good option too like 2001LS8 said.
I got 42's in my truck making close to 400 to the wheels and with the tune and new MAS it idles and drives like stock. |

Already made a few tunes for different things from 4th gear locked for dynopulls to valet tunes. You will like it a lot. It is nice to tune things yourself versus waiting for someone else to do it and then spending an arm and a leg to do so.

If every psi increases the temp of the intake charge by 15 - 18 degrees: - then 4psi = + 72 degrees over outside - then 7psi = + 126 degrees over outside if the IC can get a 77% efficiency in cooling (which they claim) - 126 degrees * .77 = drop by 97 degrees. So I'll be left with only a 19 degree increase at 7psi.... That's providing that the cooling issue is simply caused by boost ![]() |

There are mods to increase flow through the cylinder heads, bigger radiators, better intercoolers, larger intercooler tanks, etc. They all help...but the single biggest problem you have is the (h)eaton. Those damn things just create too much heat. That is why everyone who gets serious about their car swaps to a Whipple or Kenne Bell. And quite honestly, the new Whipple that's out is absolutely the most amazing blower on the market. It's flying off the shelves to the tune of about 5 to 1 to the KB with the SVT boys. They are insane with their efficiency...and low charge temps.
I wish you the best with this because it can kill your whole project if you can't work it out. Limiting boost with the Eaton is without a doubt your first priority...and you may need a larger pulley for that. The intercooler is your next best step since your math is very good. It is amazing how well that will help. Ensuring that all intake air is taken outside the hood is another priority. If you're sucking in heated air to begin with, you're sunk. I sure hope you find something minor here! |

What is the weak link for the stock internals? Pistons, rods and bolts? I know the high compression ratio isn't forced induction friendly. Is there any overlap on the stock cams? Superchargers are more intolerant than turbo when it comes to overlap. |

But other than the occasional piston grabbing due to the clearance issue, there are a lot of very high hp Cobras running around just fine. It's all in the tune. |
I will save the bigger LS power numbers to the crowd (Quik & crew) with more money remaining in their wallets, as I am about tapped out with my current car project.

I was just about to purchase a 35-125 uni ford EFI Nitrous Express WET kit for my 2001 V8LS with 85K miles but I would like a little more input first. First and foremost I want to make sure I dont blow my motor. Of course the nos guys tell me my engine will be just fine running a 75 WET shot but then again they said my car could handle a supercharger on top of the nos and I'm not so sure of that. Obviously you prefer the dry-kit, I just wanted to know why you would choose that over the wet kit and what you (or anyone else) recommend in regards to the following:
- brand (if you think it matters, I was going with NX as others have) - usage (frequency, WOT vs. push-button, rpm range, etc) - accessories (heaters, purge kits, etc) Most importantly I want long lasting performance with little or no nitrous related problems to the engine. I know alot of this depends on how you use it, and I'm fairly confident I'll be easy on her. I live in MN so I am only planning to spray on the weekends maybe 3 or 4 months out of the year. Thanks in advance. p.s. What about detection by the dealership if I do fry a piston or something? My buddy who also runs nos on his V6 firebird - also under waranty - told me all I need is an oil change and nos is almost undetectable. Another guy told me a mechanic could tell the second he opened up the engine. Which is more correct? Thanks. p.s.s. Up until now it looked like this guy had the optimum setup, only maybe with a 75 shot. Check it out: http://forums.llsoc.com/index.php?showtopic=11514 |

Talk to Modular Powerhouse, VT Engines, or Modular Depot for having a 4.6 built for you. I am having my 4.6 billet SB built by VT because they turn out one mean product and stand behind it 110%. If you were to get the built rotating assembly itself and do your own install the price would drop significantly from the $4,550 I mentioned above. That was a billet racing engine I was talking about, a forged one will be much cheaper.

You wont need to get new heads unless the ones you have now are really messed up. Much much easier and less money involved in just having your current ones reworked and swap the cams out along with the springs and maybe the valves/guides and whatnot.
What my $2,000 amount was if you just get the forged rotating assembly and install it into your existing block yourself. Not too hard and kind of fun. No real reason to go with a full longblock unless your existing heads are shot and you want to pay the high premium for it all. ![]() |

i checked out vt...their shortblock is $3495...i can get a longblock with the s/c for $3750 from my ford dealer...dont ask how, price is for me alone. |

Not trying to knock anyone's tuning preferences here but such things as spark timing retard and also spark plug heat range are some other things that are best addressed so as to prevent an engine blowing. ![]() |

the 'rule of thumb' is to decrease your spark by at least 2 degrees per 100hp. Most nitrous guys end up going at least a degree cooler plug at 100shot as well - while change to a standard cooper plug with a different gap. the nitrous reacts badly with the platium in our OE plugs. the only way I know to change your spark and fueling curve is to use the SCT and flash the PCM with new curves. so if you are reducing the nitrous jet - aren't you simply reducing the shot? I not trying to call you out - I 'hang out' with the local racers sometimes here - 75% of them have a nitrous bottle in their cars, colored purge plumes all over the place..... but less the a handful actually have tuned and put a bottle through their engine. Most of their installs a for 'show' only. I want to understand when you say 'I run a 100shot no problem' if that is really the advice you are giving because you have figured it out... I ran 100shot only a few times - before the SCT tuner was available - and the a/f ratio was way way way off - I would never recommend it without the tune. |

Like I said If you post what brand jets your using and size I can tell you what you should expect.... |

I could never get my a/f good all the way through the rpm band using the fuel jet only - I ended having to cut back down to a 75shot. |

Never trust any one item 100%, EGTs and Widebands have certain lifetimes as they are both chemical. Its best to compare many things, EGT vs WB02 vs. Spark plugs. Good tip on the copper plugs, they've more than saved a few engines between me and a friend. They are good for showing detonation too if you pull them after a pass, there will be traces of black and white specs, even if its not bad enough to crack the porcelain. |
