Usual problem, stick to NA or try my luck with Supercharging

I have LS3 in my 2gen Camaro Z28 racecar, it´s 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 someone´s interested. I´m from Finland so that have torque in Nm and power correlated from engine, not wheels.

But, to the point. Instead of that 470whp i´ll 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 take´s it and is sufficient enough, except injectors ofcourse.
That seems to give little more hp even in NA engines, so i´ll do that, but otherwise i´m 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 don´t bring any other major "problem" but i´ll have to use side mounted charger. No quick change NA works with manifold mounted chargers.

Procharger (P1-SC maybe?) is what i´ve 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, i´m 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

 

Turbo over supercharged if you want my say-so. The low end power of superchargers is great, but can you get it to stay hooked?

 

If i´ll go to forced induction, it´s somesord of superchager, not turbo, i´ve played my time with those and don´t 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. There´s cubic inch limit on circuit racing and that´s 381cid max on 1300kg weight class which my car goes to.

 

Ill preffer a procharged setup for drifting. I dont know much about road driving but seems to me like youll receive better benefits from cooler engine temperatures with the centrifugul supercharger. Then again idk about road racing lol

 

Go the Supercharger route.

 

good luck either way you choose but man i got to say you can ****** drive thats for damn sure! you normally see japanese cars drifting but i guessed you prove everyone wrong..keep up the good work!

 

I can't see a Supercharger being reliable with that kind of abuse. The problem is not the charger but the belt system.

 

Depends on charger pretty much reckon, neither of those above takes too much power on 8psi level or so...

Friend of mine had 2 years LS2 with Procharger P-1SC-1. 10psi and 6-rib belt, no problems ever with that.

And don´t 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.
