what do u all think of my set up? NA c5 dd
Ok guys bought this car roughly 2 n a half months ago bought it bone stock
My goal was to hit 400 whp as reliabley and a lowest cost cost as possible My mods are Gm hot cam 150 for cam and 75 bucks for ls6 springs Bbk intake manifold and self ported 80 mm bbk tb 450 new (had ls1 intake before) Ppwerbond 10 percent underdrive pulley with shorter belt 140 dollars Tpis 1 5/8 headers long tubes with hi flow cats x pipe 525 dollars (no leaks very happy with them) Labor 250 to install cam n springs Tune 310 dollars Injectors fordracing 30 lb injectors 36 pounds on corvette '') by the way work get and are easy to find cheap on mustang forums 100 bucks flowmatched In total i spent roughly 2000 dollars which is less then some people spend on heads alone Numbers before headers stock injectors maxing oit 350/330 i was satifished at the time Put headers and retuned 360 hp 335 torque maxed injectors at 125 percent duty cycyle and tuner said o2s where reading right ok so replaced both front o2s and and put injectors went back for retune new numbers 377/360 what do you think for the money i spent good return ? I have a set of 799 heads laying around should i sell them port them mill them both? |

Car is a 2000 c5 m6 what do u all think it will run in the 1/4 mile woth new nitto 555r II? Please your opinons! Dont leave me hanging

If you put the 799 heads on milled you should make it, but you picked basically the worst everything you could. TPIS headers are giving up a lot compared to others out there in both performance and quality. Steve Dotten was selling some QTP Tri-Y headers and high flow cats for a good price that would give you a nice HP boost and a tremendous TQ increase. The hot cam although cheap is also leaving a lot on the table in both performance and drivability. There are many Smallish cams that drive better and make way more power that can be had cheap, The BBK intake is also a questionable choice as most would go for at least an LS6 manifold. I would Also suggest a good CAI like a Vararam or Halltech. I'd say with the Hotcam and 799 heads you would be around 400-410 rwhp tops.

Could have just done headers/medium->large camshaft and would have gotten there.

Well if you get them ported by AI , TEA or PRC you will be steering away from cheap ($1000 roughly AI/TEA for porting or PRC think is around $7-800) but will pick up 20-30 HP on top of the 20hp that stock 799's will give you. If you went that route I'd change the cam too and headers. You can get close to your goal without, but you can far exceed your goal with the same amount of work if you did.

I agreed with some point i love the quality of tpis but i agreed im leaving power on the table

people please chime in also for the 2000 dollars i spent did i get bang for buck that included injectors and tuning |
Those heads will get you 20+ stock if you mill em a little bit, so you could put those on, but a better cam could get you 20 also. Most decent small cams like the TR 224, TSP 228 or maybe a newer EPS 226 can reach 400rwhp by themselves with supporting bolt on's. The 1-5/8" TPIS headers WILL cost you a lil bit of power, but with a better cam and even stock 799 heads would put you into the 415-425 range. Heads ported could put you in the 440 range if the intake is "worked" right.

TPIS are 1 3/4 not 5/8th. I dont believe they ever made a ls header in that size. BTW I have the same headers and made over 450 whp

400 + hp
Great opinions keep em coming btw what is large split?
The reason i got this ''small'' cam was because this is my dd and i dont want for it to eat a spring or drop a valve etc that happens occasaly with bigger cams also didnt have to spend cash on stronger pushrods or timing chain or even lifters i didnt buy any gaskets nothing and the car runs great but now i think im going to just port the 799 and put some 1.8 roller rockers the cheap ones lol 150 bucks with some 600 lift spring prolly pac springs and possibly mill the heads .030 with some .25 shorter pr and have roughly 420 whp on a hot cam sounds good to me? And yes my tpis are 1 5/8 design the older design i dont regret buying then 500 bucks with x pipe and hi flow cats and there gel coated and i intalled them myself what a bitch to get them in them but the cars felt way smoother all around and no nasty gargulling on decerleration anymore also my cat back is weird it has little one inch holes on the back for exhaust to pass lol how do i post pictures? |
The split I was refering to was the difference between the 219 intake duration and the
228 exhaust duration. Many LS cams are single pattern or use a 4* split. The longer exhaust ( 9* split) duration helps when you have a more restrictive exhaust. I like your idea about the 1.8 rockers, lift would be like .556 and with ported 799's it should run pretty good . Stronger pushrods are highly recommended tho. |

325rwhp on a dynojet is a lot for any tuner to screw up....Did he offer any feedback? I would be looking at hardware and a new tuner to be safe
