i have 98 six speed and just curious how much hp would i have or be close to ..my mods are K&N, free ram air mod, port polish and descreen MAf,4.10 gears,hurst shifter and gutted cats with flowmaster 80 series ALso i just recently sold my 99 30th aniversary trans i have heard they have more hp stock for stock thanks

 

305 rwhp same tq as for the 99 no real diff

 

the K&N, free mods, port polish and descreening were all disregarded with the installation of that flowmaster . .. flowmasters are really restrictive, maybe moreso than the stock exhaust, its a 98 so no ls6 intake, . . . im guessing . . . 305ish too . . . . get a cutout or a different exhaust and it'll be around 315ish, . . (a few HP's more with a cutout) . . .

 

300-315 depending

 

I'd say 280-290 depending on how your PCM reacted to descreening the MAF...the 4.10s will artificially lower your numbers.

Descreening the MAF on a stock car without tuning for it..

 

295-300
