I'm plannin on puttin a cam in my A4 99 trans-am in the next month. I'm wanting to a cam that will put me around the 400hp mark with bolt-ons. Would the comp cam 224/228 with a .581/.581 lift and a 112 LSA do that? And what size torque converter would i need with that set up? Also would it be realistic to run in the mid 11's with this cam, LT headers, intake, drag radials, and torque converter? Any advice is appreciated.

 

Get at least a 3500 stall. 11's are within reach with good tires. I'd like to see what kind of numbers and times you put down since your set up will be similar to mine.

 

anything less than 3500 would be dumb

 

i run the 224/226 comp cam, it works pretty good on the 112lsa, less lift thought only .571. Might need ET's to break 11's. Will see when the tracks open up and i learn to drive. 400whp would require some serious heads and more cam imo. you can see what my mods to power laid down in my sig. I'm gonna need some serious traction to break 12's i dont think the nitto's will do it...

cnb what kinda #'s you got? Our setup is similar

 

Sam, my baseline is almost exactly the same as yours. I made 295/324. I don't have any numbers with the 224/226 yet. I used to have the GT2-3. As soon as I install my Yank SY3500 I'll get some numbers. By the way, the lift on my cam is .569.

 

Was that dyno done with only the cam swap? Meaning everthing else(mods) the same only difference the cam?

 

nope. baseline was lid/filter/catback/nitto's

afterwards, was all mods in post..

dyno was about a week apart but similar temps iirc. Run's were unlocked of course.
car was tuned with ls1edit

 

Hlow often do you go to the track? Do you drive the car everyday?
Mid 11's and 400hp from an A4 i would suggest a TSP 231/237 or a TR230 or bigger and a yank SS3800 or a 4200 stall.Most A4 guys with mid size cams and coverters run 12-12.4 in the 1/4.So thats why i suggested a large cam and converter.

 

I was looking more towards the 224/228 rather than the 231/237 because of the reliability on a daily driver that goes to the track often. I was also thinking you would need a big stall(4400) for the 231/237and I only have a 3800 stall. Wonder what I could get out of it. BTW I run 7.4's in the 1/8 now stock internal.

 

I don't go to the track often. I'm just wanting something mostly for street racing, and some strip. Also how steetable would a 3800 or a 4200 stall be if i did decide to go with a larger cam? I don't drive the car as much during the winter but i do drive it a lot during the summer.

 

See i drive in the city 99% of the time at or below 35mph. if i want to break the law i go up to 40mph (10 over). the min lockup speed is 35mph iirc. GAS MPG with my setup is about 9mpg city i kid you not. This is because i drive 2 miles to work. 1 minute warmup (springs/winter) on each way, 2 miles, then shutdown. Alot of traffic lights/etc. Might be a 20 minute drive home one day, and 5 minutes the next.

on the freeway she locks up fine, but since they dropped the "lidar" zone to 30mph and i got nailed for 68 in 35 a week before it switched to 30mph, im chilling on the streets here. $305 ticket, ouch. So you really gotta be careful with a big cam and alot of city driving, you might push your hp up and kill your low end torque, and be stuck unlocked doing 2500rpm all the way to work (no joke). I'm sure my mpg would go up to 22-24 on all freeway, but thats not me. I'm hoping my tuner can make the car go well lockedup at 35mph without any surging/etc or i might just drive the corrado to work. The vw is more a start the car, and drive it, 5 speed. Oddly the mpg sucks on the vw cause i run a cool thermostat and the little 4 banger (supercharged factory) only hits 180F by the time at work, so im in cold start enrichment for a good bit of the ride and cold air. (The pacesetters really a good job making the heater box warm up faster!)

things to chew on. A4 high stalled cars are not nearly as friendly in heavy city traffic as an m6 would be.. Before the verter it got fantastic mileage,fwiw, i had 2.73's before as well. the 3.42's probably eat up some of my mpg, but 9mpg? thank god i only drive 2 miles, or i'd go poor.

The 224/228 or my 224/226 would make a good nitrous cam, if thats your schtick, btw, but who has the $$ for a stage 4 flp tranny after you smoke your trans after a few track events. not I.

 

9mpg is pretty bad, but i'm lucky enough to live in a fairly small town, not a whole lot of lights and not a whole lot of traffic. What would be the smallest stall you could go with if i decided to go with a cam like the 224/228 or the 224/226 on a 112lsa. I have thought about installing a 100 shot of nitrous so that and one of those 2 cams might give me better 1/4 times. What would you think of going wiht one of those 2 cams, a 100shot "dry" nitrous, and a 3200 stall?

 

The couple of cams already mentioned would be pretty rough in an A4 that is mainly a street machine. I haven't really tried selling it on this site, but I have a new Comp 228/228 .570/.570 114. Was going to run it with my 3600 stall. Having a stroker built now. Give you a decent deal if you want. Should lope pretty nice, but nothing too crazy. Or you might want to look at something similar to it. Single pattern on a 114 lsa would be great for an A4 street racer.

 

All of the larger cams suggested here should get tunning to make them streetable. With a good tune they are all fine for street/strip.If i always drove 30mph or lower i would buy a beater car to drive. That would take the fun out of driving ANY car.You could just get a tr224 and a 3500 stall or use the cam u got. Some people hit high 11's with setups like these. You said mid 11's so i suggested going big. If you use the 3200 stall and your cam dont expect mid 11's thats all.Although its not impossible its just unlikely

 

What kind of times do you run with your set up?

 

How much do you want for the cam? Shoot me a pm with a price.

 

W/O the cam FTRA and ported TB i ran a 12.8 on street tires. With those mods and nittos i think i can get a 12.3 if i can pull a 1.6 60ft time. But i hope to have headers by spring so that will put me close to the 11's. I will also have my shift points at 6400.With headers pulley and ls6 intake i think i could hit high 11's no problem. But thats still 40hp or so from mid 11's

 

well my injectors hit 102% DC at 6189rpm's. So i wouldn't dry a 10 shot on my motor. I'd think long and hard if you got 26# injectors about spraying on top of a cam/heads/intake etc..

You need to pick a diff verter to spray too, the tci ssf 3500 will stab flash to 3800rpm's and hit like a ****, you might want a lower stall and lower STR if you're gonna blast 100 shot. Hell leave the stock verter in and spray on it that would be a blast The lower the rpm's until your rods bend in half, you spray the more torque you make. My "beater" that i drive (corrado g60) went from 150wft/lbs@2800rpms to 306wft/lbs @ 2800rpms with a 40 shot of nitrous. old 1.8 litre. Insane scthuff. Too tempting to use. I was sucking down bottles all over the street/freeway. Lucky i didn't go to jail. 2600lb car with 306wft/lbs sure does scoot on the freeway in 4th/5th gear thats fa sure.

 

yeah if i get a 100 shot i'll upgrade the injectors, but if i do decide to go with the 100shot i'll go with a smaller cam, somethin like the tr224. I'm really not wanting to go wiht anythign bigger than a 3500 just because i'm not real fimilair with stall converters so i'm not sure how it'll drive.

 

you probably wanna run slicks with a tci ssf3500 and nitrous. Without it you might get away with nitto DR's. I've been told my setup will blow off the nitto's at the track as is, and i've demonstrated it several times on the street. I wouldn't dare run street tires with a tci ssf 3500. That would be dangerous imo.
