what up... im looking at 2 different head and cam setups. my car is a DAILY DRIVER, ALL STREET..NO TRACK.. i want the best setup that will be reliable, make most hp, and easy on valvetrain... im looking at these setups for head and cam:

prc 5.3 heads w/
tsp 228/228r
tsp 231/237
or
mti 2e heads
x1 cam
g1 cam

i will have all bolt ons like lid, headers, pulley, tb, ls6 intake, 3.73 gears. i also plan on running 3200 stall....just would like to hear your input..

 

None of those cams will be "easy on the valvetrian." To do that, you'll need to look at some of the old grinds with low lift.

 

well, let me repharse that...which setup would be best suited for a street only daily driver...

 

YES....

both combos will produce comparable power and have similar streetability.

what is your hp goal? with the heads you can go smaller on the cam and make good power.

have you thought of some AFR or Dart 205 heads? with the smaller intake size it will produce better power down low, which is good for the street.

good heads with a mild cam like the 224, you can easily make 400rwhp.

 

i did think about going the afr and 224/581/112 route. but i think the prc outperform the afr and is awhole lot cheaper. i would like to atleast put down 415rwhp..and i know its doable. tsp with their prc 5.3 heads and 228r cam put down 408rwhp.. some people tell me to go big, and some say since its all street you wouldnt need a bigger cam than a 224. i guess i want something thats a lil rougher than a 224.

 

well...for what it's worth...TSP claims they got 415rwhp cam only with my torquer....

i dynoed 382rwhp with it.

but any of those cams, with any of the heads should yield you 415hp on a good tune. the TSP 231/237 will definately do it.

the advantage of the AFR heads is the smaller intake runner. which builds power down low better. the 5.3L heads flow as well (or claimed slightly more) but they have an intake runner size of 230cc which will make good power in the upper rpm, but at the price of some power down low.

however the intake runner size of 205 like on the AFRs or the Darts will build power in the lower and mid range, with only a slight sacrifice in power up top. and remember peak hp numbers are nice for internet racing, but power across the band wins races!.

i notice the AFR heads only come in the 66cc combustion chamber, which is fine, but the Darts have the 62cc which will increase the compression (still within 93 octane range) a bit more which can make more power.

the darts are well priced too.

talk the guys on the tech lines, and see what they say

 

As far as today's standards, they're all streetable with a good tune. There are getting to be more people running even larger cams like the Magicstick, TRex, G5X3, FM14 etc., daily.

Since you have gears, you might as well go larger than a 224. Might want to look at a higher flashing converter than 3200 though.

 

i would like to try and run that 231/237. i hear it pulls bad a$$ up top too.. i would try a 3600 stall, but im wondering how the drivabilty is with that size stall..im not sure what will make more hp afr with 231/237 or prc with the 231/237

 

As big as you are talking of going ... 3600 is the minimum. A 3800 would be better.

Keep in mind there is a difference between "streetable" and a "daily driver". For a big cam to have reasonable manners, the idle is going to be pushing 1000rpm or more. Also to make that 420 rwhp, in all likelyhood you will be looking at 30lb injectors.

Throw in 3:73s and a high stall, what this all adds up to is something less then great gas milage ... 11 to 12 mpg or less, around town. Maybe 15 or 16 highway ... if you can stay out of it, less if you get addicted to the power.

 

im not too worried on gas mileage..yeah good point on the daily driver streetable..basically man, i want something that pulls hard all the way up to redline, and pretty much give 03-04 cobras a beating..i know i cant beat all of em...hey which would be better suited for a daily driver that makes the most hp...futral f11 or f13?

 

a daily driver that makes the most hp is kindda an oxymoron. the more power it makes, typically the less streetable it is. and vise versa.

i would say the F13 is streetable from what i've read on the board. it's similar to my Torquer and i drive mine on the street.

and V6toZ28....do you really think milage would be that bad? my cam has me running 24mpg on the highway, and 18 in the city. granted it's a 6spd with stock 3.42 gears, but still. i can't imagine the auto with 3.73s would be that much of a reduction in milage.

 

In order to handle a big cam - even a moderate cam - an A4 needs the idle tweaked up. In order to give it some street manners, with a high idle, you need a high stall - which requires more throttle to get moving ... I get about 10 to 11 mpg around town, around 16 highway.

 

What you need to look at is NOT "most hp" but instead power under the curve.
