You may find with the headers and full exhaust you'll need a little more pulley to take full advantage of it. You will run out of high side likely though so it may not be worth it.

I have a JMS FuelMax and after we got into the +180 whp (w/cam) range we ran out of low side: the high side was showing instability along with low side not reaching commanded levels at that point. You can do it but high side will be the driver in your setup more than low side. At best it will offer some better stability on high side. Here is my thread on the install I did: https://www.camaro6.com/forums/showthread.php?t=569721. Now I think it is around +220 whp, I can't remember.

I think putting more pulley in it will have me making too much power for the stock fuel system with an M6.

The 2650 will be out of the price range without a doubt, not even on the radar. I have ZERO intentions of ever wanting to make 800-900-1000 HP so it would all be wasted money to me.

I had good luck with my setup so far... see SIG for details.
I do have a single nozzle meth system though.

Option A with E85 sensor.. Even if you don't have good access to it you may find a gas station or shop that has it one day and throw in half a tank for race day. Noticeable gains for sure.

I was under the impression The 2300 and 2650 wont build boost as fast as the stock blower because of the displacement, can anyone shed light on this?

I have 18 A10 with 2650 103TB roto fab texas speed heads 2019 zr1 cam dsx lowside AR headers and xpipe and 80mm pulley meth kiy. My opinion on the A10 its a perfect blower 2650 with room to grow. Im no road course expert but the power is more mid range to top unlike stock blower . I cant speak on manual transmission id assume momentum loss between shifts and boost? Either way i know lots of members making the power level you want with stock blower .

Nice numbers! I'd be 30-40 hp down without the meth, so right on target.

Don't have enough fuel system to run E over the mid 600's my man. Also, when I drag race it's at Beech Bend (Bowling Green KY) and there's a 100 octane pump over at the Corvette track if I get there early enough.

Since budget is an issue and 700whp is the goal, I would to Kong, Jokerz, Modern Airflow Dynamics ported blower, 103tB, biG gulp, etc....

Should get you close to that 700 I’m sure. Meth is not as scary as some say. Also long as you do the maintenance and maybe get an extra pump to have while the other is being serviced every 18 months and you should make crazy power. Just a thought.

I gained 70whp from a 2.3 upper

Do you do anything else other than:

- Baseline
- Add Pulley
- Dyno Tune?

I have a 9.45 lower ready to install going skip the port and add the methanol injection. Hopefully by the end of the summer it will be installed and tuned. Meth is cool like Marko says just takes maintenance. I wouldn't run 100%meth prob the boost juice mix which is 50/50. Alky control meth kit. Not going to use the windshield washer kit either that would be a pain to maintain and get to. Its worth the extra coin for the ease of access

I have a 2.5 gallon tank for the meth. I have only done about 6 real pulls on the car and a dozen little pulls. I run straight meth. The tank is still about 3/4 full. It last a lot longer than you think. 5 gallons of meth/M1 cost me $60 so I don’t really notice the added fuel cost.

I would encourage you to get the SC ported. That coupled with a 103TB will net you 50whp easily.
