To be or not to be, NA or FI? LS3 to 550-600whp range Usual problem, stick to NA or try my luck with Supercharging
I have LS3 in my 2gen Camaro Z28 racecar, itīs main use purpose is drifting but i also use it to vintage circuit racing.
Engine related specs:
-Stock LS3 out of the box
-Lunati Voodoo 65602 cam, 227 / 238 0.50" and 0.583 / 0.600", 112/108
-Lunati gold double spring set.
-Pacesetter 1 3/4 longtube headers +2,5" dual exhaust with X-pipe
-Stand-alone Tatech ECU, no MAF
470whp/ 490lbft from with old 3" individual exhaust, reckoning that now bit more torque with new exhaust.
Dynograph if someoneīs interested. Iīm from Finland so that have torque in Nm and power correlated from engine, not wheels.

But, to the point. Instead of that 470whp iīll need to get it to the 550-600whp range to keep Camaro somesord of competitive at Drifting in here, in circuit racing Camaro is powerfull enough as it is.
NA route:
I can use E85 quite easy, my fuelsystem takeīs it and is sufficient enough, except injectors ofcourse.
That seems to give little more hp even in NA engines, so iīll do that, but otherwise iīm open for suggestions?
-Does Fast LSXR 102 intake give how much advantage in this system?
-Head porting?
-ITB:s?
Only "problem" with this is, that i can use E85 in drifting by regulations (I can easily use two different ecu maps, for 98 octane and for E85), but not in circuit racing so raising compression is out of the question, and that would be the thing that give more advantage with e85?
Supercharger route:
If this, need to do it that way that i can use car charged in drifting (and with E85, with charger there is no other way in my opninion)
And drive circuit races without charger belt and with pump gas, regulations again.
This donīt bring any other major "problem" but iīll have to use side mounted charger. No quick change NA works with manifold mounted chargers.
Procharger (P1-SC maybe?) is what iīve had in mind.
Other option is HPS 2.8l charger (Kenne Bell) but that bit silly for sidemount, advantage with that is price, would get sweet deal for one of my sponsors from that.
Thoughts, advices?
And sorry for language mistakes, iīm from Finland.
...ad if wondering, Drifting, 2gen camaro??? Yes it can be done

This car is sick...been watching these vids on youtube for years lol. Anywho, the only way your going to get 550-600whp N/A is by stroking it but not sure if that's allowed or not with all the regulations. You can definitely get more power out of the stock shortblock but you won't meet your goal. Throw some boost at it and you'll easily meet your goals...good luck

If iīll go to forced induction, itīs somesord of superchager, not turbo, iīve played my time with those and donīt want especially to drift car. And not traditional roots either.
Centrifugal chargers seem to give pretty good top end also
And stroker, forgot to mention, out of case. Thereīs cubic inch limit on circuit racing and thatīs 381cid max on 1300kg weight class which my car goes to.

Friend of mine had 2 years LS2 with Procharger P-1SC-1. 10psi and 6-rib belt, no problems ever with that.
And donīt laugh...
My previous racer was tiny Opel Kadett Coupe -76, i did that with BMW M5 S38B36 engine and Eaton MP112, it had belt troubles with 8 rib belt. But, just changed belts after every 2 races and no troubles, smallest things to do between races.
