fwd dsm

[Dsm2Nv]

I was just wondering whats the difference between our fwd car's and others I've noticed high power fwd dsm's out there only going mid 12s and other cars with around the same power braking into the low 11's is their any reasonable explanation for this?

...are you meaning a fwd dsm with x mods against an awd dsm with same x mods...?

or a 20 psi fwd dsm against a 20 psi civic, both having mostly the same mods...?

Because DSMers are normally cheep! Your not going to be running 11's on a fwd with stock suspension, stock bushings & cheep street rubber. All fwds are at a disadvantage but when both prepped equally a DSM fwd will keep up to any other fwd. 11's aren't a problem for a fwd DSM with proper tires.

Thats what i mean a 20 psi fwd dsm vs lets say a srt4 both with about the same mods making about same power but the dsm will go high 12s and the srt4 will go mid 11s and even if u switch cars results are preety mutch the same .

weight is a big issue a little hatch back weighs like 2000 lbs and our FWD come in around 3000 or so

Daren i went up with a couple of Buddy's to Cayuga last weekend that had a fwd dsm that run 12s and a srt4 that hit 11.5. The thing is they both dyno around the same power both have the suspension bushings and decent tires but the dsm couldn't brake out of the mid 12's. We thought it could of been driver so since they were also Buddy's they switched cars and same results.

Most other cars are lighter, so it takes less power for them to be fast.

Civics are 600+lbs lighter, the B series engines people usually swap+turbo have higher compression which helps the turbo spool, and the cams(esp. vtec) give them great top end.

Srt-4's have a huge stroke, which helps. They aren't any lighter, and don't really have a better power-to-1/4 ratio. They come stock with somewhere around 240whp, and run low 14's/high 13's.

Suspension and gear ratios have alot to do with it as well. I see the suspension in honda's modified to a much higher extent than most dsm's, and the trannies have much tighter/shorter gear ratios.

There ya go!



Also dont SRT4's have built in LSDs??

What were the 60' and MPH of the 2 cars?

Exactly the 60 and mph will tell all.........

Im thinking apart from Weight, Shifting, Tranny mods, and the 60 time... It would make a difference. Lets get the time slips and such or at least the WHOLE Story.

+1 with SRT-4s came with LSD after the first year they came out i think, but i know for sure later models had LSD.

 

[Dsmj89]

If it was an 04-05 srt4 you can bet it had an LSD.
Also remember, as stated above, our cars are heavy cows, , get a cf hatch and a custom rear hatch glass out of lexan or whatever other material is light, may cost a little but it'll deffinately reduce the weight back there.
Keep the weight in the front cause that's where the fwd need it at to keep the front tires planted.

Hey Ruben, what were the slips on both these cars? Like some have said, believe the SRT4 comes with an LSD, which would be a big advantage plus probably made more torque if the two cars dyno similar hp numbers? Also what tires were each running? If my car stayed fwd I almost guarantee I'd hit 11's this year on the DR's

For the Hondas, like has been mentioned their much lighter but they normally lack alot of torque as well which on street tires really helps them out. A properly driven fwd DSM with slicks or a good set of DR's should be able to net times pretty close to the awd equivalent. I think part of the problem is most of the guys who actually want to spend some money & go fast, just switch to awd, so fwd platforms don't get the chance to perform. Also I think alot of the fwds aren't set up properly either, which makes a huge difference. Fotr example, I've heard many times from fwd guys that they can can spin the tires all through 3rd & I was making alot more power then them & never had an issue. Difference is my car was setup descently. If you have stock suspenion, rubber busings, 205 sized all season tires, stock open diff etc, of course your going to have issues putting down the power.

Im not sure what the slips were but im going to try to get them from them and post them up here so you guys can take a look at it.
