Anybody do the trickflow kit hci setup and have experience with trying both the street heat and track heat?
car will have the TF hci kit, longtubes, 373s, 5 speed, 75mm tbody, 24lb injectors
90% street driven, weekend warrior type car
what do you shift at with the street heat, and with the track heat?
 
I have had BOTH. The street heat will gve you a little more low end but for YOUR combo go with the TRACK heat. You have 3.73's to make up for low end and TH will allow those heads to breath PAST 5000 RPM.
 
I really didnt like running my car hard much but when I got on it the street heat would die at 5k on the button..shift 5200 max (nothing bad for a mild set up). WHEREAS on the track heat I would get power past that so if I wanted to would shift at like...5800-6k max. That was perfect but again, my car was never track and rarely driven like that, lol.
 
i went to a track heat from a cobra intake with afr, tfs1 cam, and lost about 30 rwtq at 2500 rpm. torque never caught back up, but it did make peak hp at 6k vs 5400 with my cobra.

since then i swapped the track heat upper for a street heat upper, but i have no n/a results to give you.

me personally i would go with the street heat--unless you go with 4.10's and a tfs2 cam and wind it to 6500.
 
I went with the Track Heat and stage 2 cam. They seems to match up better. I also have the 331 to help with that low end torque situation. :D

Waiting on a few more parts, then it'll be time to fire it all up.

Street heat, stock heads, stock cam retarded 4 degrees, and I shift at 5500 on my stock tach, however accurate that is.

Get the track heat, I only went street because I couldn't swing heads and a cam and plan on swapping to the track heat upper when I do so.

My thoughts would be along these lines

As for low end torque .........

Usually a mid length runner will kill a bit of it

However you got 373's and LT's so that will offset some of the loss IMHO

Spark table optimization will prop up a soft low end as well ;)

anyway ........

I've never paid much attention to the rpm capabilities of the TFS 1 cam
but
If it pulls pretty good up top .............

I'd do the track heat upper and capitalize on its top end efficiency
and
Try to get the best of both worlds or have your cake and eat it too :D

Another thing ...

I think 30# inj's would be more appropriate for your needs
unless
You run them at elevated fuel pressures

oh, also I gained ALOT of rwhp going from Street Heat to-> Track heat. I forget exactly what it was but it was considerable.

I did NOT lose ANY TQ on the dyno .. I gained upper RPM RWTQ. Same dyno.

With MY combo, the track heat blew away the street hands down. Felt like a 32 valve, lol.

With a mild combo, the street heat blows away the stock intake and nice low end.

Again, I had TFS Heads and around .510 lift cam. I did not go with the TFS cams.


One a side note: I am starting out with a typhoon on my 408. I am not sure how it measures up to other intakes or even the track heat intake BUT I am going with a specific combo on mine and it is just one piece of the plan. I don't know what rpm to expect upper end though. Low end is no worries hehe.
