Just say it was 300 hp at the crank that would make it the 270 at the wheels. You need to remember that had a blower on it

I would have to agree from records I found that the s/c model only lists .7 of a sec faster in a quarter, seems it should have gained 1.3-1.7 for an alleged 40% HP increase. I do however believe it is possible to push these motors to 350-380 with the correct set up of getting the air/fuel in/out effectively near 7k rpms
I imagine emission standards prevented them from hitting that mark, because saving the environment is more important than horse power.

I'd think the ss1 has a 12-15% reduction.

Ummmmm Your on the wrong forum for that topic. Start looking at liter to HP ratio of common engines and it will make you think. |

Ltr vs HP vs rpm actually. It all depends on how well it will flow.. the valve size might restrict I don't know, but that is simplistic thinking. The IRL Modified the 4.0 to get 10,500 rpms and 650 hp, along with a crazy compression ratio.
I have already done that yrs ago, I understand the dynamics trust me.

Do you know what the IRL engine was? It had no common parts with the Northstar |

Completely different heads, I know. I wasn't suggesting our motors to do that, I was only stating more rpms= more HP. Depending on how much flow our engines will allow. I do not know what it is, nor do I claim. All I know is a modified exhaust should allow more cfm, than factory. I don't know how much that is either, I just wanna find out when I get the money to dyno tune it, hopefully.

The engine has 2 additional balance shafts if I remember correctly and the block is much smaller even with the extra shafts. |

Performance engines are good to break the 100hp per Ltr mark. I knew what you were talking about.

Guys, some disagreeing back and fourth is perfectly allowable, but I see this thread heading south quickly. Lets attempt to keep the posts semi on topic. I know all of these comments relate to the topic, but no real helpful information is being shared here.

^Shelbyracing is always being overly opptimistic about his engine and build.
"Let me drop in a Shelby motor it has 320whp." No the bloody hell it doesn't. The Shelby 4.0 is nothing more than a regular 4.0 and sometimes they have VIN 9 cams in them. That's not going to net you the 50 extra HP that Vin 9 4.6 has. Use your common sense, add, subtract.
With my cammed/built 4.6 with headers and all the other crazy stuff I'm doing I'd be lucky to see 300whp. That's really pushing it.
Caleditor can you do anything for my car or not? I've already asked you but you just ignored my question. It's a 95 Aurora, 4.6 swap, CHRFAB 272 cams, .020+ Wiseco 10:1 pistons, eagle rods, ported intake manifold, ported heads, ported TB, CAI, headers w/ reworked crossover pipe (no longer a choke point), true 2.5" mandrel bent duals through an x-pipe, built 4t80e w/ EP LSD.

I like being optimistic, but I said I'd be very happy to see about 250-275 whp. That's not too difficult to believe is it?

If you have not been to our site we offer a Dual-Flash setup for the LS1 PCM's. We also have a Dual-Chip setup for the OE Northstar PCM's from 1996 to 1999. The Dual-Chip is our own product and it works the same way as the Dual-Chip. We offer the Dual-Flash for the 2000 to 2003 PCM's I know you say you don't have a 2000 Aurora, but you do they are just titled as 2001 The DUAL-FLASH allows GM GEN III and similar PCMs physically contain two flash chips, allowing the user to switch between two separate calibrations  What is the OmniTuner DUAL-FLASH? The OmniTuner DUAL-FLASH is a member of the OmniTuner line of products by Digital Inflection Corporation. This device allows you to install two separate flash chips in one Powertrain Control Module. Most GM Generation III applications are supported but when ordering specify which PCM you have so that the DUAL-FLASH has the proper flash chips installed. GM used both 512k and 1 megabyte flash chips in the GEN III PCMs. The DUAL-FLASH replaces the flash chip that was installed by the factory with two separate OEM flash chips that individually appear to the PCM as a single flash chip when selected. Through the use of a switch of your choice you have the ability to select which one of these flash chips is used by the PCM. You have the ability to switch between flash chips only when the ignition is in the “off” position to prevent accidently switching between flash chips when the car is running. Possible applications for the DUAL-FLASH include tuning a vehicle for multiple fuels, assuming this tuning is compliant with emission regulations. You can use ethanol based fuels when available and switch back to conventional fuels when desired. Additionally you might choose to tune one flash chip for fuel economy but leave the other flash chip stock. Any tune that you can flash to a stock PCM can be flashed to either one of the flash chips of a DUAL-FLASH enabled PCM. NOTE: Insure the DUAL-FLASH has an image that is compatible with your PCM before installation. Unless the DUAL-FLASH image has a compatible PCM operating system you will need to reflash the DUAL-FLASH with the correct image before installation. The DUAL-FLASH comes with a default tune for a GM 12200411 PCM which is compatible with many GM PCMs. How to operate the DUAL-FLASH Operating the dual flash is as simple as flipping a switch. While your vehicle’s ignition is in the “off” position flip the switch to position one for the first flash or position two for the second flash. You can use a standard toggle switch to keep things simple. You should be aware that changing the position of the switch while your vehicle is running will not switch flash chips but when you turn the ignition “off” and back “on” again the switch between flash chips will occur. So, it is best to only flip the switch when the ignition is off to avoid selecting the wrong flash chip at startup. It is also important to note that after turning the ignition “off” you must wait 20 seconds before turning it “on” for the DUAL-FLASH to switch. This is because it takes about 20 seconds to completely power down your PCM.  |

Can't you buy the software for the cost of the tune? What is the cost of said credit? Nevermind. www.hptuners.com/order.php$499 with 8 credits (enough to tune 2 vehicles). I'll look into it. I might just buy it. I've always been pretty good electronics/computers. Edit Again: Why are none of the vehicles listed on the compatibility chart on their page? www.hptuners.com/products/vcmsuite_vehicles.phpor did I just have a brain fart and it is't een the right software haha? |

We do the Northstar's in Hex and or one of the ones listed below
We own HP Tuner's, EFILIve, TunerCat OBD 1 and OBD 2 tuner, Moates TunerCat RoadRunner, Digital Horse Power (DHP), Tiny Tuner, OmniTuner, TunerPro, JET's DST, Wester's DDT, DiabloSport, WinOLS, IDA Pro, SCT and I have probably forgot a few

I would use a hex editor. I guess if I wanted I could use TunerPro also.

I have 3 calls in to get some help with the def files We use TunerCat to tune OBD1 cars. TunerCat does not have any Northstar defenition files released. The reason is that the calibrations are not mapped out the same. I know a guy that we are working with to get his cliff notes on the Northstar def files. |

As you can see John has a few 4.9L def files for the same year cars John Told us that it would be a big project to support OBD1 Northstar's The way John has it listed he has 6 possible def files for 1991.  |

Just to clarify the price. As of today we will change the limiter for $250. This is because of the work required to do this.
We will sell a performance tune of MINE for $350.
The performance tune is not a Wester's tune. The PCM will not be going to Canada to get tuned. This is a tune for the 4.0L Aurora's That I have built

I can do it too, now!! Figured it out last night. I called it the RT tune. If you don't believe me, check my youtube videos, I have a video of an Aurora going 137. After I figured out how to tune it last night, I dynoed it and also went and ran a 1/4 mile. There was so much smoke, my tires burned the whole 1/4 mile. Being that the results would be so mind blowing, I will not be able to show the results. I did figure out that a tuned Aurora is too dangerous to be in the public, so this morning I had it smashed, along with all the video and info I had on how to do everything. Sorry, guys. But, I may be able to do it again, or maybe not. Do what you ask? I can't really say that either, but maybe I will, or maybe not. Ok!! No. IT'S ALL TRUE!!!!!! LOOK AT MY VIDEOS!!!!!!!!!!! (The dates on the videos are not accurate, they are all from last night)
