how much lift is ok?

**TmaxicanA** · 03-02-2008, 11:05 AM

..ive asked a few people about this, and have got a few different answers. thought i would just make a thread about it.
for a car that will be driven every day, just like a normal car.
...how much lift will be safe, i really don't want to hear a valve hit my piston when i stomp on it and it red lines just a tad to far.
one person has said no more than 540 or so..and some say 580's are alright
could some of you guys who have cams give some feedback on what you have? thanks in advance for the help.

and then there is one numbnut i know who has a 641 lift on his stock camaro that he is putting in...well i know where that will end up (i'll post pics when it happens)

Depends on the grind.

Newer blanks allow for more lift without clearance issues than older grinds.

It has been said that High lift cams wear out Springs faster but in reality it's the aggressive lobes that put stress on the valve spring more.

the cam i was starting to look at was 224/588

Depending on the lobes, you should be good to go with a cam under .600 lift as long as you have upgraded springs and hardened pushrods. My cam is a 228/230 TFS grind with .585/.585 lift (112 LSA) and I went with the Comp 928 springs and 7.4" hardened pushrods. I don't anticipate I'll have any trouble with this setup and it should be good to get you to 11.9 with supporting mods. The cam NHRA mentions above would also seem to be a great fit for your goals.

I have an older "custom" Comp Cam with 226* duration and .595" lift on the intake and exhaust. With 918 springs and hardened pushrods, it sees well over the factory rev limit on a regular basis. Never any P to V clearance issues.

BTW, with an A4 and 3600 stall, it goes 11.67@115...maybe quicker this year since I made some changes to the previously bone stock suspension.

Here's a shot of a recent datalog just before the 1-2 shift...

mr nhra is where I got my cam idea from..he gave me a lot of helpful advice ...so with some new springs the lift would be fine at 588 ..and duration at 224 cause I don't think ill have enough to by me a dd for awhile so this things gotta last I have the pushrods already all my basic suspension will be done with the tax return..and im not sure if ill keep my stock maxed out converter ..how much did that 3600 cost you. is it easy on the streets.

Mine's a Precision Industries Vigilante 3600. I think they're about $750 or so by the time they're shipped. Being that it still retains lockup in Drive and OverDrive, it's fine on the street IMO. They say PI Vigs are a little looser than claimed, so mine's probably more like a 4000 stall, but still plenty liveable with on the street....and I love it at the track.

This happens at every launch, which is fine by me, lol.

it will mainly depend on how you drive. i maybe lost 2 mpg

**rel3rd** · 03-05-2008, 12:14 PM

At first, I lost a LOT...but since it's been in the car for a while now, I mainly just cruise and very rarely give it much more throttle than need be.

**TmaxicanA** · 03-06-2008, 07:51 AM

I drive like grandpa moses would on week days..im the one people fly by cause im going to slow....but on the weekends I have the middle finger raised and a sign on my window that says get the f$#% out of my way...im a bad driver on nice weekend days/nights

i think if you want streat use go with a lop over 114 i will reccomend a cheatr cam from thunder racing
"99-TR-CHEATR-CAM Thunder Racing Custom Camshaft
"CheaTR" - 214/230 .601/.575 117 LSA. Off Idle-6800 RPM Power Band. Broad power range. Works well with stock exhaust manifolds and catalytic converters. Stock like idle. Minor tuning required on automatic transmission cars. Responds very well to nitrous. Due to the fast ramp rate of this camshaft, the use of 1.8 rockers is not recommended. Double valve springs and titanium retainers required for this cam. "
