Need help. The plastic pulley that came with my Paxton 1220 has ridges (looks like where the pulley was put together form 2 pieces) and is real scuffed on either side of the ridges. I suspect belt bounce and slippage. Anyone got a number of a steel or aluminum replacement pulley? The stock...

1990 7 Up Convertible – $14,500. The car currently has ~15,000 miles and is in pristine condition. It has never been driven in the rain by myself or the original owner, I have lowered the top maybe 10 times. The car comes with documentation, including the original purchase papers, window tag...

Feeler - what would be a fair price? 1990 7 Up Convertible – purchased by the original owner in California as collector car and had only 3000 miles in 1999 when on a weekend drive the thermostat froze and the engine overheated. Instead of rebuilding the original engine the owner, who was then...

Another lousy, what's my hp thread, but there's no dyno within 200 miles so here goes. Mods should be shown below: 340 hp, crate engine w e303 cam, x303 heads, cobra upper and lower intake, 65 mm TB, 1 5/8 shorty headers, 8-9 psi boost @ 6000 rpm. Major HP resrictor is stock exhaust except for...

Will this work with my Paxton 1220? http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=260672378951&ssPageName=ADME:X:RTQ:MOTORS:1123. Seller won't say yes or no. It's a dual o-ring, piston valve. Sorry url doesn't work unless copied in. The valve is a metal Bosch look like listed...

Who has experience w/ street slicks, how much will they help? Also if I do hook, what are the chances of something breaking? I don't want to change rims or do suspension mods, would just like to be able to spin less in 1st and 2nd.

Can't keep it hooked up even coming off @ 1500 pm. How much will a set of p235 60 r15 G Force TA drag radials improve traction over my p225 60 r15 Kumho Ecsta MXs? Thanks; Mike

Need some help with the radiator cowl. Can I paint the ugly thing? Any help apprciated.

Here's a question for a buddy. He's got a stock 89 convertible with a newly installed Vortech V3 making ~6-8 psi boost. He want's to know if he'll get more HP/$ if he installs a bigger throttle body and MAF, or opens up his stock exhaust (does have magnaflow mufflers, everything else is stock).

OK how does a FMU work? Does a 10:1 FMU @ 5 psi with base pressure set @ 40 psi = 90 psi or 50 psi? Seems to be at least two schools of thought. FYI, the guy at Paxton said it would be ~60 lbs.

Help please,just got an innovate wideband and need help locating the sensor. Does it have to go in front of the first cat (closest to the header) in a stock exhaust system? There's only about 2-3" there and seems like it might overheat the sensor. Sure could use some advice.

My fuel pressure valve has stopped reading. I believe that the connector that screws onto the schrader valve is plugged/messed-up. Anybody know where I can buy just the connector that screws onto the schrader valve? Thanks, Mike

Not really a tech post, but want to say thanks to all the members who have helped me with everything from window motor bushings to supercharger install to choosing mufflers. You guys, and ladies, are the best!!

Need help in deciding on a mid pipe change. With the mods below how much will I gain if I go with a catted mid pipe (still is stock from headers to the magnaflows)? I'm trying to keep the car as stock as possible in appearance and sound but I hate giving away HP! Thanks, Mike.

Replacing the water pump and lower radiator hose on my LX. The new hose does not have the spring to keep it from collapsing. I understand that the new hoses are not supposed to need the spring but since the pump is higher volume I thought I might insert the old spring. Will that be OK? Will...

I'm trying to decide how bad I need a dyno tune, the closest tune is 2 1/2 hours away. With the mods below and about 5-6 # of boost, what HP should I be seeing at the rear wheels. Doesn't seem as fast as I had thought it would be after the SC install. Also any tips on tuning before the dyno and...

Guys; I know that a dyno tune is the best but the nearest is over 2 hours away. Given my mods shown below will a mail order custom chip be any help? The car runs fine but I feel like there is still hp to be gained from better timing and A/F control. If a chip might help, which do you recommend...

I'm ready to get an x pipe with cats for my 90, see sig for mods. Which one do you guys recommend, needs to have bung for o2 sensors. Also how about an estimate of the rwhp I should be getting before and after the exhaust change. The nearest dyno tune is 2 1/2 hours away and I'd like to have...

Need some help. Does the msd 5462 boost/timing control that I have provide for a hotter spark or does it only retard the timing under boost? If it doesn't provide a hotter spark what is my best option for ignition upgrade? Add a 6al or replace the 5462 with a msd 6btm? Thanks

Question on my lower intake gasket - cobra intake, gt40x heads. The gaskets I took off had 2.0x1.2 port openings (I'm guessing a Fel Pro 1250) the new gaskets are Ford Racing M9439-A50 with 2.2x1.28 openings. Sure looks like very little room for error on the gasket match to the manifold. Looks...
