Is this a good combo?

reddy351 · Aug 12, 2006

GT-40 or Explorer upper and lower
Thumper E7's (219/155cfm)
"E" cam (it's an auto)
24# injectors
FlowTech unequal shorties
catless h-pipe
190lph pump
adj fpr
3.73 gears
J-modded trans
CAI

Pretty good package, or not? Am I wrong or is this good for about 270-280hp, to the wheels? I was going to just throw a blower at it but, I've decided that the extra cash can go to dropping it and putting some 17x9/10 wheels and possibly Cobra brakes on it. I'm looking for 13 second ets and a great over-all package. Is there anything I'm forgetting about? Opinions? Anybody running this combo? I'm sure it will need a tune. I think I'll have a chip burned, instead of a tuner.

You MAY reach that goal

but

When using an auto trans ..................

I've seen they seem to be inconsistent when you use dyno charts to compare their results.

If you had a stick trans ... then I'd say you might reach that goal

IIRC, you got a Tweecer ........... sooooooooooo

You might find 10 to 15 more with it ... depending on parts used

two major things that you are forgetting about are a better torque converter around a 3000 stall, you could get one from Edge Racing for around 600-700 and also your forgetting to get a shift kit. Unless that stuff comes in the J-modded trans which it might. A lot of guys will tell you that you will only get about 260ish hp out of this combo. Thumper heads dont make that great of power put give you good torque. Also you might want to go with something other then flowtech headers, they are kind of the worst made headers from what i have heard. Some heads you might want to look into getting are some edelbrock performer, there aluminum and they also put out number in the range you want. You can also find them pretty cheap from 650-800. If I am wrong with any of this someone just please correct me.

Where can I get Performer heads for $650-$800? Is that complete?

Danman765432 · Aug 12, 2006

Well they are used but you could pick them up on corral.net

Here is one example: i have seen them for cheaper though

No heads come complete

You gotta add rockers

If you go stud mounts ...... which are my first choice

you'll need guide plates, and hardned pr's as well

really is that neccessary for afr165s and twisted wedge heads as well?

JJ95GTID · Aug 12, 2006

Except for elevation I am in the 13's with stock cam, rockers, pushrods, throttle body, MAF, fpr, and injectors. I paid $724 for the Y303 heads, $300 for the intake and elbow. Just see my sig for my frugal setup. If it ain't there then it is stock.

reddy351 · Aug 12, 2006

I like the frugal build. 13's would make me happy. The torque would be the ideal focus for a street driven car. Maybe I can re-use the OE cam for this combo?

"Complete" when it comes to heads usually means springs, valves, valve seals, etc. In other words, ready to bolt your rockers and (if they fit) use your pushrods and such. I wouldn't expect new heads to come with rockers.

J-mod is a type of "shift kit". It uses the OE valve body plate, modified with different sized holes and replaces some internal parts of the tranny. We'll see how it works. Guys that have it, love it.

Would it make sense to just replace the heads and intake with Explorer parts. I would think I could really save some $$$ with those parts.

I assume that when these cars came from the factory, they made somewhere in the neighborhood of 190rwhp. 260 to the whheels would be a HUGE improvement over that.

Then I could add the supercharger later, to better parts.

Thanks for the input, guys! Keep it coming!

Not entirely sure but ... I don't think TFS gives you a choice

Just a few reasons ... I don't like ped mounts .........

Not as stable at higher rpms
Not as easily adjustable
No flexability in adjustment without shims/different pr's

You may disagree ... but ... you asked

I believe studs are better and justify the additional cost

Grady

JJ95GTID · Aug 12, 2006

I agree with Grady on the adjustability of the rockers. Mine do make the infamous ticking noise. The stock PRs are just too short. I bought the shim kit but I will need to get longer PRs to use them. Or, I have been thinking of getting the Steeda shaft mounter rockers with the adjustable PR cups. Kills two birds with one stone by going to a 1.72:1 roller rocker and not needing to get longer PRs.

If i were you, my combo would read like this:

95snoozer's combo.

GT40Ps / Typhoon intake / Comp XE270

he makes 295/321!

I gotta agree with Kyle

He has some of the best looking curves for a GT40p head based combo I have seen ....... and I've look at quite a bunch of em

reddy351 · Aug 13, 2006

Ok. How much work has he had to do to the heads? A lot of porting, or what? I can remove smog bumps and do some bowl work. I'm actually pretty adept at that.

I like the price of the Typhoon. In fact, there's one on Ebay, right now with the 94-95 elbow, a 70mm TB and the upper and lower for less than $500. That's right up my alley.

Would the 24's be enough or should I go up a little? Keep the stock MAF? Anything else?

Sounds like the Typoon,GT40P's,XE270 cam,24# inj,NO adj FPR (read that thread) and a tune. Plus the other supporting stuff that I mentioned in the first entry in this thread. Sound right.

Breathing on this side of 300rwhp. Easy mid/low 13's. How is the driveability of that cam?

Thanks a lot for the help guys. For a few more bux (or maybe the same amount) than I was originally planning, I get quite a few more hp. Nice!!!!!

Is this a good combo?
