I just got my first cobra last month and I want to get a twin screw supercharge. i am planning to run 17-19 psi and using the stock fuel rails +hood+mainfold+dynomax ss catback+X pipe. also do u think havin BAP is just enough to have 590-600rwp?
Bap will work at 600 but the 2.9 whipple is gonna make 650ish on pump gas mine made 669 on the the stock pulleys and I just don't think a boost a pump will keep up but others will chime in

since the stock fuel system won't work with 2.9 can I use the stock hat+GT dual pumps+PPRV delete instead of the fore hat i am realy tight budget since i am getting married next week LOL
Get the 2.3 if you are wanting 550 - 600. Either way make sure you don't skimp on the fuel upgrades.
what is best affordable fuel upgrade for 600rwhp? i am really tight on budget.
do it once and do it right. twin GT's/Fore hat/Dual FPDM/SD 63 lb injectors. that setup is 700rwhp capable. and If you plan on getting the 2.9 a BAP isnt gonna fly anyway
as far as the 2.3 vs 2.9 debate I contacted Whipple directly they said the 2.9 is good for about 40 rwhp over the 2.3 @ 17-18psi and also has cooler IAT2 temps as more air is being compressed per screw rotation... also more room to grow in the future, should you ever plan to up the boost past the stock pulley
Whipple is right cause when I did a before and after test I picked up 49hp at the same boost level. 23lbs was the boost between the two blower's. Also I have the complete Lethal/Fore fuel system and I ran out of pump and injector. I just purchased a bap and I am also going with 80's.
If you notice I said that my boost level was 23 not 18. Also WHIPPLE said you should see up to 40hp gain over the 2.3 at the 18lb boost level not me. I am stating what I made. Why cant you make that distinction?Are we going thru this again?
Are you suggesting that he's gunna make 49 more hp with a 2.9 over a 2.3 at 17-19 lbs of boost? Again, your post seems to suggest that!
Remember your last proclamation you posted to this effect?

Gets interesting at post #68
You putting the 2.3 up against the wall at 23 lbs. He's looking to run pump gas on a basically a stock engine not a highly boosted engine running race fuel. For some reason you have a hard time making that distinction.
To the OP:
If you plan on keeping the engine to run on pump gas you will probably be better off with the 2.3. It should respond better at lower boost levels and your not tuning as much mass as with a 2.9. If you are thinking of going BIG later down the road with race gas or E85 then the 2.9 will be a better bet. 17 lbs of boost is 17 lbs of boost between both Whipples and the engine won't care where it's coming from. It certainly won't make 49 hp just by going to a 2.9
