I see...
Do you mean in addition to GIAC stage 2 an additional 50 hp?

 

Correct. My understanding is that this thing will produce about 600 wheel horsepower or 700 crank hp on 93 octane which is a gain of about 140 hp over stock.

But just as importantly, if the GIAC Stage 2 plus tune works as promised for the intercoolers, no more aggressive cutting back boost at high Rpm's which is just as important as peak power. I mean when I launch, I absolutely feel it is vicious out of the hole but then by about 80 or 90 and certainly by 100 acceleration starts dropping off pretty quickly.

 

Don't set your expectations too high, the compressors in the stock turbos simply cannot flow 600whp worth of air on 93octane. The intercoolers will save a few degree's of timing pull due to iat's on extended hits.

 

I'm a 20 year commercial and insurance litigator and trial attorney by trade, not a tuner, so I don't really know exactly how much the car can produce on stock turbos other than what I'm told by people in the industry much more knowledgeable than me.

I certainly do think with this latest set of mods we will probably be bumping up against the outer limits of the stock turbos (absent adding something like water/meth injection or nitrous which I would never have in my car).

I do think that once these mods are installed, any further power increase will require something much more dramatic like a turbo upgrade. I know that Champion is developing one now and is testing/dynoing/datalogging it but my guess is that the release is months away.

I do know that Champion and GIAC have been working on this upgraded ICs/upgraded tune package for a very long time (since last year) and have done very extensive testing and datalogging for many months. This was not a product rushed out to market to try and race to catch up to someone else's competing product before proper testing/data logging and verification was done. And frankly as someone who really wanted it I've been quite frustrated by how long the process has taken but the results will almost certainly be worth the wait.

That being said, I'm sure I'll take it to an independent dyno shortly after I get my car back--probably the same shop that confirmed that my car was suffering from severe heat soak issues on GIAC Stage 2. Also, the results/gains will also be tested and proven (or, hopefully not, disproven) when I take the car with these new mods to meets.

 

I really hope you are correct
Too hot in SoFL
Good times!!

 

Sure is. Just came home to NYC from two weeks in Boca. Steambath there this time of year.

 

For my understanding the other company that are making "IC's Tune packages" is ByDesing & COBB and for sure they are not rushing anything to finish the package, they also have long days working on this.

Just to keep clear the point you just say... maybe you are reffering to other company that are working similar packg?

 

There are others working on ICs. All I know is that the Champion product has been in the works for a long time. It sure does look like ByDesign and Cobb have been working hard on their product and based on their strong reputations I expect it will be great.

 

OK, no problem!

 

Sure...I'll send a PM shortly. I will also say, though, that our first batch is sold out, so it will most likely be a couple weeks before I can fill your order if you place it now.

Glad to hear you're enjoying it Karl!

 

SDG what are the dyno results from your car from stage 2 to stage 2+? what kind of HP gains did you see going to catless? Does the IPD plenum fit?

 

SDG's car is strapped to the dyno right now, as we're doing some before/after testing with a few different hardware configurations that SDG requested we look into.

However, I can tell you that strictly going from Stage 2 to 2+ on his car, adding only the intercoolers and revised software, the car picked up 30hp and 44tq at the wheels...on 93 octane pump gas. I think that if he had a cat-less exhaust we'd see slightly higher numbers, but in the interest of keeping his neighbors happy, we're sticking with cats on his car. Overall I think it's a nice improvement.

 

I Won't post the Dyno graph of my car in until Champion formally releases their upgraded intercoolers with the GIAC stage 2+ tune. But I will share a few things.

While it is true that the gain in peak horsepower in my car is about 30 and in wheel torque is 44 that does not tell the whole performance story.

Specifically, there are points in the rev range where the gap between the horsepower and torque produced by the new ICs and GIAC stage 2 plus tune and the GIAC stage 2 tune is as much as 50 wheel horsepower and 64 wheel torque in my car. That is huge. Also, as I had hoped for, the gap between the power produced by this new GIAC stage 2+ and the stage two is quite large at the higher RPMs. This is clearly, as GIAC promised, the Stage 2 plus tune not aggressively dialing back boost and timing and high rpm's as it does with the stage 2 tune and stock intercoolers to protect the intake air temperatures from getting too high.

Champion did not get a chance to test the Tubi catless race exhaust on my car versus the my europipe because they didn't have one in stock. That is a test I definitely want done.

As to whether my car's heat soak at events is gone I will take it to events and let you know what happens.

My sense is with the Europipe Versus Tubi catless I am leaving something like 35 wheel horsepower on the table. But there is no question that the europipe exhaust is quieter in terms of sound levels but still lets you hear turbo and wastegate noise and popping in sport and sport plus on letting off the gas.

 

SDG,
It all sounds really good, can't wait to get mine. The next 1/2 Mile races I'm in the exotic class and this is my competition 1-MP12C 1-650s 1 F-12
1-huracan 1-Longboarder ( Adam ) and a P-1 So we will see how the tune compares ( I lost to Adam by 3 cars last time) as long as I can get it and have it installed in time, Tom when are you releasing data and my order? It's been really soon now for awhile? Does the IPD plenum fit?

 

The IPD Y pipe does not fit the Champion ICs unfortunately. We tried it in my car and the carbon tubes exiting the Champion ICs do not fit the IPD Y pipe. So my car did not get the IPD Y pipe installed. My car has the IPD plenum and that fits just fine

I also had champion install the FVD headers and dyno hem. Unfortunately they lost both power and torque relative to stock headers. And they lost massive amounts of horsepower and torque at lower-midrange RPMs. Needless to say I am not using them and went back to stock headers. To me those headers are a complete waste of money at least with a GIAC tuned 991.
