Far as I know, my car only has a Borla exhaust with headers, and a Vortech Supercharger. Vortech states 550hp and so I probably have around 470rwhp. I see some claims of upwards of 550rwhp, but is that possible with just a tune? Seems like those figures would require additional modifications.

 

How many pounds of boost? I have seen many car make over 550 with just the blower.

 

can you do this without a tune?

 

Let me clarify as maybe my first post was a little confusing. With the supercharger, which is rated as 550hp, could a better tune increase that amount? Or is more hp generally derived from just increasing boost? Also, if boost is bumped up by say 2 lbs (basing this on 6 lbs of boost as a base), is there a fairly good chance of engine failure at some point with everything being stock? I'd like to get around 525rwhp, so I just want to bump up around 50 more hp than current.

 

All the Vortech blowers I see on here are more than 470. We really need more info as which Vortech blower and is it a Vortech kit? or other like A&A, do you have a intercooler?

 

A good tune with 6lbs of boost should be able to get you above 500rwhp. I know for a fact my tuner has tuned cars with just those same mods and made 500+rwhp.

 

Tuners, if they have any sense, and most do, tune for power "safely". It's possible to get more power out of just a tune, but your risks of engine problems go up. Engine problems on a boosted motor are often catastrophic..... = expensive. Meth allows a more agressive tune hence more power with the same boost. Otherwise, it's better to up the boost a bit, add meth, and maintain a safe tune to get more power.

Edit: 6psi with a crappy/max power tune is more dangerous than 8psi with rich afr's and a bit less timing.

to the above point, They risk doing it in on the dyno, Or leave you set up for later tuned on the ragged edge. Weather changes so do your fuel needs. thats why I like tuner, I made 515 on a mustang dyno where the new ZR-1' make about 505. Then they go to other dyno and make 550 , Shows the Mustangs are tighter! But I still have a safe tune!

 

I do have an intercooler, but I purchased the car with the S/C installed, so I'm not sure which specific Vortech model it is. I figure it was mildly tuned, and was told the dyno was 460. Do I really need more? Probably not...but 500rwhp sounds nice, lol!! I will not get a tune until next year, but my tuner will only tune for safe levels. I don't have enough $$$ for an engine failure, and riding a bicycle for a few months while it gets fixed doesn't sound appealing.......

 

Do some research. Save your pennies and do it right. Find a shop that has a good rep. Your goals aren't that far fetched. Should be easily, safely, and economically attainable. Many are at you HP goals reliably. The big money has already been spent. The equip. is there....just needs a few more $ thoughtfully thrown at it.

 

If you dont' have the money to pay then don't play!! I would leave it as is until you get enough money to replace something. I mean come on you have 460rwhp do you go to the track or anything even?

 

If I bought a car with S/C installed, and I was unsure of the tune, I would immediately take to a reputable shop and verify the tune/ A/F ratio..
You are not that far from A&A corvette shop, the west coast guru for supercharged cars..http://www.aandacorvette.com/ It would be worth the $$$ for him to dyno tune the car, and get everything right. After Andy is done, you will be able to enjoy the car with out fear of blowing the engine. It will take only a few seconds under boost to toast your engine..Better safe than sorry..

 

Yes you could get more power. Just make sure you do it right.

Looks like your not that far from A&A, call him and setup a time to drive up there and he will tell you if its his or not and will look it over for you as well... The best part is you get to do a road trip

Thanks for the info! Funny thing is, I purchased my car in Oxnard...guess I should find out who did the tune, might have been there at A&A already! So I have been on that road cruise, but it's not too bad!

 

[QUOTE=Rock'n Blue 08;1567836280]I saw that 505 hp thread. Livernois Motorsport just did a pull on a Dynojet, 571 RWHP and I believe the RWTQ was 548 for the new ZR1.

 

If your car has headers, and the stock size pulley on the supercharger, then you're down on boost by approx. 2 psi. First thing I'd do is get a dyno pull and check the A/F ratio. Then, swap to a smaller pulley to get the boost back in to the 6 psi range. With a good tune (not a radical tune) you should see 500+ rwhp, easy.
