Headers HP for a auto?

by **Chef solara** » Sun May 04, 2003 4:31 am

Has anyone heard or seen the dyno sheets from JP on the auto yet?
I know that eric posted that they were looking for a auto but have they found one yet?
Question, what's the stall speed of a stock torque converter, and one of a high performance torque converter.
And when the value bodies are upgraded what does that do exactly?

Does anybody have any info. for me. I would really like to get the headers and all I need is the info.
JP hasent writen back yet.
But maybe flipside or eric can.
THanks very much.

I don't think there are any dyno numbers available. I know Jim@FA got his headers and said he felt a huge power increase on his auto but no dyno charts to verify it

Yes, but keep in mind that he had also installed his upgraded cylinder heads, and possibly done some bottom end work, as well. The huge power increase is due to synergistic effects of multiple upgrades. He felt that the headers complimented the heads very well, and did add some additional power. It's kind of hard to use his case as an example because most other people's engines won't be as "developed" as Jim's.

I Completely Agree. Headers will do more for his car especially because he is running higher boost.

We'll just have to wait for some dyno charts

so...any numbers on the auto? L8r moe :evilbat:

Not at the moment. My buddy Jim from NorCal might know soon. He just picked up a set of JP headers for his Auto S/C'd Solara with upgraded pulley. I'll ask him if he had the chance to dyno it.

I think he only dynoed around 214 or 216 fwhp, and that was with a 6 psi pulley. He also blew one of his knock sensors. I was pretty surprised at how low his numbers turned out. He's experimenting with the stock pulley and adding race gas to get the octane up.

Wow that's not much at all. Thank goodness for 5 speed manuals!

Yeah, considering the cost of the supercharger and the headers, and then the cost of installation, I've got to think that Jim is a little disappointed. Aside from Yanks, I can't think of many people with an auto tranny who have been very thrilled with the supercharger. I would have thought that adding the headers would have had a much bigger effect. It's hard to believe that the difference in drive train loss between the manual and auto would be that large.

I don't think there ever was a baseline run so we have no idea what he started with.

by **cdssolara** » Wed May 07, 2003 2:31 pm

That's true, and I don't mean to imply that the headers aren't giving him additional power. It's just that I figured that with the 6 lb pulley alone he'd be getting more fwhp than what he got. With that and the headers, I figured he'd get at least 240 fwhp, even with the auto. You have 273 and that's with a 5.5 psi pulley, exhaust and intake (if I remember correctly). He has an Injen intake and Apexi WS exhaust, so it's a fairly equitable comparison. Assuming some sort of difference in drive train loss between your manual and his auto, I figured 240 would be a reasonable estimate. If it was me, I'd be disappointed in the figures that he got.

by **pecora55** » Wed May 07, 2003 2:59 pm

yea 240 sounds about right if he is getting 273, as i recall i thought there was a diff between like 20 whp with nothing done with it, something like 153 for auto stock and 170 something for manual if i remember it right....

Well, count me as one more auto owner who likes the supercharger. With the 2.75" pulley as my only mod, my 0-60 time was improved by 35%. I couldn't stand to drive the car without the S/C. Between the extra weight of the convertible and power sucking altitude, the car is a dog when N/A.

woa...35% increase in 0-60 with auto ???now i understand that u have an upgraded pulley...however with the stock pulley i only noticed about a .7-.9 sec. difference....before s/c my car did about 7.5 i think...now with the 4psi pulley(stock) it does about 6.4 or so...so with a 6 psi pulley ur saying ill be under 6 secs easy? IF thats true i cant wait for my car to be done i have a 6.2 psi pulley..hehe...by the way: FLIP...any comments? L8r moe :evilbat:
