Godspeed 90mm Throttle Body + Intake manifold

[jrhdohc]

Cool. one of my friend with a 180sx has a Power FC, Z32 MAF, S15 turbo & injectors, and R32 GTR pump, 235 front and 255 rears on 17inch rims, Cusco LSD, Tein single adjustable suspension, Project Mu HC+ pads, down-pipe, cat delete, and exhaust. Great weekend track car and touge. Not sure of the actual hp he's making but fun well balanced car. Good power from 2500-redline. Not a dyno queen! haha. Although, S13 & R32 push more than S14/15 R33/34 and of course RX-7 and S2000. Just use slightly larger rear sway bar to cancel push (adjustable is best to fine tune it's balance) Away I could ramble for hours about Nissans. Later and good luck.

... I've yet to actually see one over 500hp. Its just not wide enough. It can't fit a wide enough tire and the vehicle dynamics aren't there for me to do what I want with more than 450hp...ish. Which I'm sure will be enough for now. Believe me I was really really dissapointed the moment I realized that my 240sx was so limited....Modified by TheKon at 10:48 AM 11/25/2009

I, as well as others on here, run the same tire that 8 sec mustangs run...width has nothing to do with it. You can get plenty of tire under the car, and can control it fairly easily.

[TheKon]

Right but when you say 8 sec mustang you're talking about a drag car. I'm going for I guess what you guys would call "Time Attack". I love drag racing but it gets kind of repetitive. If I need more power I'll build it bigger. I'm starting with a forged bottom end. As upgrades continue it'll just be a matter of aggressive head work and bigger turbo/fuel system. So it won't take much for me to continue upgrading if I'm unhappy with my results.

you compared our 240s to a solid rear axle outdated mustang....

No I didn't. You're taking my post out of context. I was using a hyperbole to describe an undesirable effect that is caused by an excess of power over traction.

[Largekid]

solid axle, yes. outdated...not so much. the foxes were arguably the best factory drag car built. There are IRS cars out there running 8/9s as well, its just easier with a solid rear. I was refering to getting the power to the ground, and the poster above me saying the 240 isn't wide enough to keep power on the ground. It obviously is, and if you are having problems....drive better.

The S Chasis does have issues with putting power to the ground. It goes beyond just the tires. It has to do with the rear suspension geometry. The S chasis has poor weight transfer from front to rear. As the rear squats the tires camber in causing less of a contact patch resulting in loss of grip. Also as the rear squats the suspension tightens up causing a loss of grip as well. You can change certain parts to make things softer but the geometry of how the rear setup works will stay the same. Guys cut 1.5 or 1.6 60ft times on the IRS setup all the time but your not really hooking good till your hitting a 1.4 or lower 60ft.

Oh no... I cant believe I read most of this thread. Its so off topic.

I read the first page with the intention of adding usefull information. Instead, I've become significantly dumber and dont think I can offer anything helpful now.

Kbye

it would be nice if they made a Q45 flanged throttle body simular to that so it would bolt on...

The factory Q45 throttle body has a lot of bulls*** on it

[TheKon]

That's why the car gods have blessed us with screw drivers, wrenches, cuttings wheels and anything else that's makes the other species jealous of our opposable thumbs!

If finances are your constraint, remove your stock unit and have a local shop tig a sheet-metal manifold.

I can get you a custom built sheet metal plenum tig welded to RB runners for $500. I'll PM for more details.

I feel like this thread discussed some of the most annoying subjects in the book.

-knock off vs. name brand-sr vs. rb-good and bad of a S chassis drag car./solid axle vs. IRS

did i miss any?

it looks like a 20 post gap from something that dealt with the original point to now.

lock or get back to useful info on the subject?

greddy(past and present), ISIS, godspeed, ebay, etc mani owners should chime in, not speculators, and band wagoners.

I highly believe that the "name drop" of greddy has alot to do with their prices, not so much R&D. (flashing back to domestics) Think how simple the greddy mani is... why did it go from $500 to $900+. When you can get higher flow heads(2 items) for domestics V8s for same price if not cheaper. What do you think requires more R&D, a head or a intake mani? I know it may be like comparing Apples to Oranges but its something think about.

when you have a company like Greddy largely supported by a Viral crowd like honda you get popularity mark up. Plus the price jump could also be attributed to Greddy Japan filing for Japans version of bankruptcy cause people to raise their prices all while Greddy USA is doing fine and is still doing good business.

Greddy makes good and bad products as someone has stated, after the few examples ive locally seen and heard of the most recent Real Greddy rb25 manifolds being sub par to "knock offs" or third party sellers. I may be just a bad batch since greddy does get their manifolds made in china, but I have heard of no bad reviews from those on this forum who have bought the ISIS manifold (from RawBrokerage) my vote is for the ISIS and it will be what Ill buy this winter/spring.

i think ive killed enough of everyones time, mine included. Time to go for a drive!
