My 2017 A&A + METH Setup
 

Hey everyone, Here is what i have so far. 2017 Grand Sport with an A&A Supercharger plus Meth. Below is a few pictures and my DYNO from A&A.

Still not installed, is ARH 1 7/8 headers catted and an AR Xpipe. Anyone have an idea after a retune what the numbers may be? Love this group! Yall are amazing!!!

You making 662 whp without the headers?! U need to add the headers asap, its building pressure on the engine

Going in this Wednesday, the kit went on at 700 miles I am around 1000 now. so it should be fine. I haven't tracked or beat on it yet.:willy:

Must be a happy dyno unless that is a Ysi. I have the A&A Ti blower with the 3.6" pulley, TSP header and meth and I made 662/598. Another member here made just about the same on the same setup.

I'm excited to see how much headers will gain. Maybe consider a pulley swap since you're going in for a retune.

Anyways. Your car looks absolutely killer

Edit: I just took a look at my blower and it designates V3-Ti so I can only imagine that you are on the Si blower. There is a member on here that also has the Si kit, meth and no headers and he made 620 I believe.

Of Course its building pressure in the engine, it has a blower bolted to the front of it.

OP: you should pick up 15-20 wheel from headers, but you will see less boost.

:iagree: If those are true number very nice. I have the same setup going to the rollers in less than 3 weeks will see what it does. Robert

The T trim is the bigger head unit. He is probably right about 9-10 psi which is the right power for what he saw with meth. It'll be a 680 rwhp car with headers. That is basically the identical setup to the novi 1500 headers and meth cars which we see 680-700 wheel all day long.

Thank you all for the feedback. It is right around the 9-10 PSI range. I am on the V3 also. The headers and Xpipe with a retune is a must. I honestly don't care as much with the numbers as I do staying as consistent with the testing as possible (Same Dyno, same factors). I go in for initial pulls Wednesday and then the Headers go in.

Which pulley are you on (it will give a size on the face of the pulley such as 3.8", 3.6" etc. im betting this is on STD smoothing not SAE. You are on an Si trim as someone mentioned earlier. I have the Si trim as well with long tube headers running 9-10 psi on the 3.47" pulley, and dual meth @ 25GPH. My car put down 638Hp and 619Tq. So, your numbers seem to a bit off, as in toooo high..

:iagree: More tuners around that will make your car do higher on the dyno just to get you to come back to them & to get your friends to come to them just for that reason a higher # on the rollers.

Every one says man that tuner really knows his stuff on this and runs to him..:thumbs::thumbs: a TUNER ON A DYNO CAN PLAY WITH UP TO ABOUT 20% OF THE TRUE NUMBER ONE WAY ARE THE OTHER. Lower are higher... Robert

I doubt you gain much. But you'll make the same power with less boost, so it'll be more efficient

Thanks for all the opinions, again the final number doesn't mean much. With the racing I do it will speak for itself on the 1/2 mile. First race for this car will be in November.

Also it is the Si blower on a 3.8 pulley. I was on the phone with A&A and my power numbers seem to be on par with the setup I am on. Mine is also a Manual so it has less drivetrain loss compared to the automatics.

On a 3.8" pulley I dont think is possible to make 10 psi. The Si trim requires the 3.6 or smaller pulley to even get close. The 3.8" pulley is only good for about 8-9PSI at best. The 3.6" pulley is good for 9-10PSI and the 3.47" pulley is good for 10-11PSI. Mine is manual trans also. Telling you those numbers are too high to be right. Most people with a 3.8" pulley on an Si are running about 575-600HP. Meth does not add 100 HP. Would be good idea to get it on a different dyno for comparison with SAE smoothing set to 5.

My Ti with 3.6 pulley, lg longtubes w/off road x, dual nozzle meth put down 700whp/650tq.
2017 GS, 900miles, automatic

Ti and Si can't really be compared..

Just posted for reference as people were talking about them.

Part of me agrees with you. However, A&A has been doing this for some time and we will see this week when I strap it it Excelsior's Dyno. God I hope it puts down like 550whp so everyone can stop overthinking everything lol. The car ran mid 160's in the 1/2 mile. Faster then the Z06 I was lined up against. As long as the tune is as safe as possible and that trap speed keeps going North, I am happy. The Dyno regardless of what it says is just another tool I am not concerned :):flaghalfmast:

Nice # I have all the parts you do with Borla cat back, with ported stock intake & ported T.B. on my car from one of the vendors in here.Robert.

:iagree: The dyno should only be used to give a person a some what good WOT tune on the car, Not doing that on the street when a person get in the 800 to 1,k and over set up. Plus on the side you a rwhp & rwtq #. But a track will get the car truly dialed in under a true load.:thumbs: Robert
