Same with my gains were measured on a dynojet, but had stock exhaust. 25whp and around 40wtq

 

Just to let you know we've been other this in the other thread. The PPE and Sikky headers are very close in performance. The only real difference was the PPE car having a better power band, but i believe this result is just a difference in dynojets.

As of now, PPE seems to be a higher quality header at a higher price that yields very similar performance gains with Sikky.

I would love to see the a/f ratios of both cars if anyone has the data.

 

^^^^As I recall my AF ratio went from 11.5 to 13 to 1.

Any plots with this on the other graph? It should be graphable if you have the datafile.

 

Great News - The Group Buy is starting next week

Lou

 

Is the final version with O2 sims?

Any $ estimates per group size?

 

^^^^The final version will have the electrical solution for the 02 simulator, PPEs 02 extender did not prove to be 100% reliable on the ISF. The 02 simulator will be wired into the harness extension, so it will be plug and play. It has been tested and has proved to be 100% reliable. I don't have it on my car, because I am using high flow cats.

The discount amount will depend on the number of folks who sign up for the initial Group Buy.

i am interested in this gb, but am confused to wether about modifying the car. So let em get this straight this is a simple plug and play header? I heard somewhere that the oil dip stick needs to be relocated , ehh whats this about? And if the header is replaced but with stock cats but with a joe z exhaust will this fail smog?

 

It may pass the sniffer, but will most likely fail the visual inspection in Cali.

 

If you replace the stock exhaust manifolds with the headers and replace the stock exhaust with the JoeZ, you will lose all four of your stock cats. Two are an integral part of the manifolds, and two are a part of the stock exhaust. Because of this, I have inserted new Hi-Flow cats in my exhaust system. Some other header owners have also done this. This would, of course, require modification to the JoeZ, but it's something any exhaust shop could handle. Now, in California, you would pass sniffer and OBD tests, but if the inspector knows what they are doing, you will fail visual.

Now, about your first question, Yes, it is a plug and play header. But, any header installation on the ISF, requires dropping of the front sub-frame, and is not a job for an amateur. It is an eight to nine hour job for a professional. And yes, the dip stick is relocated (moved forward about 4 inches).

I'm interested in the group buy these headers now have the same electrical sum as the sikky is this correct and when is the ghost price gonna be

 

I believe the PPE and Sikky headers produce produce about the same power.

 

holly hell a 8-9 hour job for a professional? what the hell is the installation cost gonna be then?

oh also how is the dip stick relocated? I just dont get how a dip stick can be relocated. Sorry for the newbie question.

 

650-1000.00

 

So it could be up to $2200 for headers when done lol?
