I used the TA Race headers because they gave the most room for a 4" DP.
I've relocated the battery to the back spare tire well. I'm actually tossing around the idea of going to a band clamp exhaust housing and running just a down pipe and gate dump forward and down through the battery tray turning outward just below the front bumper in front of the tire. That would allow the full race style headers that actually have a header on the passenger side as well vs the stock log style when I switch over to the Buick aluminum heads.
I used the motor cycle batt in the front saves weigh overall. The Front dump thing is neat, but I couldn't bear to cut a hole in my fender, so i just dumped under the pass side seat. No muffler at all and you can hear what is sounds like... not bad at all.
First off Scott those heads are an absolute work of art, what size are the valves? When did you decide to switch to E85? Only member I remember running E85 in his TTA was that guy running that batmowheel compressor wheel, but I think he sold the car. I ran naturally aspirated for awhile, but started putting the turbo stuff back on my GTA last October, just waiting for the weather to clear up to at least get it back on the road, little more to do because I gave away a lot of stuff over the years. We should meet up one day and run, not from a dig though, definitely from a roll, and I say roll for obvious reasons of course, as I ain't catching no low nine second TTA...
Yeah I have the ATR full 3" all the way along with 3" DP and 3" electric dump under the passenger seat as well. If I dump it all up front I don't plan on cutting the fender. I'd only dump the exhaust under the fender. Not sure I could cut a hole either though I shouldn't worry as much as I have cut the car up so far...10-point chrome moly cage, mini tubs and narrowed Moser 9" so far lol
Rob, no E85 for me closest station is 30+ miles away. I'll run a 93 pump and dual nozzle Alky tune and a C16 tune.
You know I haven't even measured the valves yet. The guy I purchased the whole setup from had them set up for his 7 sec Stage powered Vega. I'll have to change the valve springs since they were set up for a .600 lift solid roller...my cam isn't quite that big lol
Here is a 22-23psi run on ported stock iron heads
That was my fault. I seen 120# injectors in your signature and I immediately thought E85.
